EM630/TC6A Closed-Loop Vector Hoist Inverter User Manual Preface Thank you for purchasing EM630/TC6A series inverter. Document No.: 31010030 Issue Date: 2014-04 Version: 103 EM630/TC6A, a high-performance inverter series specially developed for hoisting, is widely used for tower crane hoisting, trolley hoisting, slewing and travel closed-loop. Default parameter settings are adjustable according to applications of F20.00 selection in the hoisting industry . Main Features:  Closed-loop vector control and steady performance at high torque and low frequency: smooth output of rated torque 0 Hz/150%, so that a hoist performs stably during start-up, hoisting and decline.  Zero servo function:

offers the second type safety protection to hoist under the condition that an encoder is connected by driving motor to hold full load in the air or let it go down slowly even when the braker does not work.  Overspeed protection: When an encoder is connected, overspeed stop protection and overspeed operation protection are provided to timely discover abnormalities of speed and braking force during hoisting to prevent slip accident.  Braker control logic: Braker control logic controls hoist to open or close at reasonable sequence, which maintains the operation safety and extends the service life of braking system.  Wide voltage input range and automatic voltage stabilization:

These functions meet torque output requirements of hoist even when voltage of power grid drops.  Wide speed regulation range: This meets the requirements for light load at high speed and heavy load at low speed, thereby improving operating efficiency of hoist. Please read this manual carefully before using EM630/TC6A and keep it properly. Before connecting EM630/TC6A and a motor for the first time, please configure the motor nameplate parameters including rated frequency, rated power, rated voltage, rated current, rated rotation speed, rated power factor, and motor connection.

Since SINEE is committed to the development and improvement of products and product documents, this manual will be updated without notice. Latest updates and additional information are available at www.sinee.cn. 1

EM630/TC6A Closed-Loop Vector Hoist Inverter User Manual Safety Information In this manual, there are two types of safety information. Danger: The label indicates that a failure to follow instructions may result in serious injury or even death. Caution: The label indicates that a failure to follow instructions may result in moderate or slight injury and device damage. Please read this chapter carefully before system installation, debugging and maintenance and always follow the safety precautions below during operation. SINEE will not undertake any damage or loss caused by a failure to follow the instructions. Safety Precautions Before Installation: 1.

Do not install inverter if the package is wetted or any component is missing or broken. 2. Do not install inverter if the label on the package is not identical to that on the inverter. Danger Danger 1. Be careful when carrying or transporting the inverter so as to avoid damage! 2. Do not use inverter if it is damaged or any component is missing so as to avoid injury! 3. Do not touch parts of control system with bare hands so as to avoid ESD! During Installation: Danger 1. The installation base shall be metal or other non-flammable material so as to prevent fire risk. 2. Do not unscrew the fixing bolts, especially the bolts with red mark. Caution 1.

Ensure that no cable strips or screws are dropped into the inverter so as to avoid damage to the inverter. 2. Install inverter at a place with less vibration and no direct sunlight. 3. Consider the installation space for cooling purpose when inverter is installed in a closed cabinet or space. Wiring: 2

EM630/TC6A Closed-Loop Vector Hoist Inverter User Manual Danger 1. Wiring must be performed by authorized and qualified personnel so as to avoid unexpected accidents. 2. A circuit breaker must be installed between the inverter and the mains so as to prevent fire risk. 3. Ensure that the power supply is off before wiring, and ground the inverter in accordance with the applicable wiring standard so as to avoid electric shock. 4. The grounding terminal must be grounded so as to avoid electric shock and fire risk. Danger 1. Never connect input power supply cables to output terminals U, V and W of the inverter.

Pay attention to the terminal symbols and connect to the terminals correctly so as to prevent risks of damaging the inverter. 2. Be sure that the wiring meets EMC requirements and local safety standards. Cables should be in recommended sizes so as to prevent accident risk. 3. Do not connect braking resistor to DC bus terminals + and – so as to prevent fire risk. Tighten terminals with a screwdriver of specified torque so as to prevent fire risk. 4. Do not connect a phase-shifting capacitor or an LC/RC noise filter to output circuits. 5. Do not connect a solenoid switch or an electromagnetic contactor to output circuits.

Otherwise, it will trigger the action of the overcurrent protection circuit or even damage the internal parts of the inverter. 6. Do not disconnect internal cables of the inverter, or else this may possibly damage the internal parts of the inverter. Before Power-on: Caution 1. Verify that the input voltage is identical to the rated voltage of the inverter, input terminals R, S and T and output terminals U, V and W are correctly connected, there are no short circuit phenomena for the wiring of inverter and its peripheral circuits, and all wires are in good connection. Otherwise, this may result in inverter damage. 2.

Never perform voltage withstanding test on the inverter, because it has been done at the factory. Otherwise, this may result in accident. Danger 1. The front cover of the inverter must be closed before the inverter is powered on. Otherwise, it may result in an electric shock. 2. The wiring of all peripherals must be conducted in accordance with the guide of this manual. Otherwise, it may result in an electric hazard. After Power-on 3

EM630/TC6A Closed-Loop Vector Hoist Inverter User Manual Danger 1. Do not touch the inverter or its peripheral circuits with wet hands to avoid the electric shock. 2. If the indicator is off or the keypad does not display any information after power-on, please cut off the power supply immediately. Never touch any terminal of R, S and T of the inverter or the connecting terminals with hands or a screw driver, or else an electric shock accident may occur. Contact our customer service personnel immediately after cutting off the power. 3. After being powered on, the inverter will automatically check the safety of the external strong circuit automatically.

Therefore, do not touch wiring terminal U, V or W of the inverter or the wiring terminal of the motor with bare hands, otherwise it will result in electric shock. Danger 1. If you need to check parameter settings, be careful of personal safety when the motor is running so as to avoid accidents. 2. Do not change the default parameter setting without approval to avoid damage. During Operation Danger 1. Never touch the cooling fan, the heat sink or the discharge resistor with bare hands for checking temperature, which may result in burning! 2. Only qualified technicians are allowed to detect signals during operation so as to prevent personal injury or device damage. Caution 1.

Prevent any foreign items from being dropped into the device during operation, so as to avoid damage to the device. 2. Do not control the start/stop of the inverter by ON/OFF of the contactor so as to avoid damage to the device. 4
