Technical Manual for EA350 Analog Pulse Type Servo Driver V101 Parameter functions: Control running of the driver cooling fan P8-07=0 : The cooling fan of the driver runs when the servo activation is ON and a warning/alarm occurs P8-07=1 : The cooling fan of the driver starts to run immediately after power on P8-07=2 : After power-on of the driver, the cooling fan will start to run when the detected radiator temperature of the driver exceeds 50℃, and stop running when the temperature falls below 40℃. Parameter functions: Set the threshold for driver overload warning based on the rated output current of the driver.
The driver has an overload protection function, which will start to generate overload curves according to 100% rated current of the driver; however, in this case, it will not directly enter the alarm state. This parameter can be used to set the threshold for overload warning of the driver; once the detected driver overload exceeds this set value, a driver overload warning will be given, but the driver will not stop running. Parameter functions: Set the threshold for servo motor overload warning based on the rated current of the servo driver.
The driver has a function to protect the motor against overloading; the function will start to generate overload curves according to 100% rated current of the servo motor; in this case, the driver will directly enter the alarm state. This parameter can be used to set the threshold for motor overload warning. Once the detected motor overload exceeds this set value, a motor overload warning will be given, but the motor will not stop running. Parameter functions: Set resistance of a braking resistor. It cannot be changed when a built-in braking resistor is used.
When an external braking resistor is used, setting shall be performed based on the actual resistance; besides, the resistance of the braking resistor shall not be less than that provided in section 2.7.1. Parameter functions: Set power of a braking resistor. It cannot be changed when a built-in braking resistor is used. Setting shall be made based on the actual power of the external braking resistor. Incorrect setting may cause damage to the resistor due to overheat or result in frequent alarm of the driver. Parameter functions:
Duty cycle of the brake pipe upon braking When P8-12 is set to 100, the brake duty cycle is 100%; namely, the brake pipe is fully open during braking; When P8-12 is set to 0, the brake duty cycle is 0%; namely, the brake pipe is fully closed during braking (no braking resistor is used). Generally this parameter requires no adjustment. If during running, the alarm is prone to occur, the user may set an appropriately larger value.
