VEDA MC MCD5 SOFTSTARTER Communication manual 1. Parameters 1.1.1 General The all parameters of MCD5 soft starter can be set by the panel and by RS485 communication. 1.1.2 Main parameter 1.1.3 Protection parameter Classified as Business 3 Parameter MODBUS address (DEC) Setting range Default F-34: Motor current FLA 0x0034 1 - 9999 Rated current of softstarter According to lectotype. Factory setting 11А. Parameter MODBUS address (DEC) Setting range Default F-11: Over current protection value 0x0011 0 - 400% 150% Factory setting The soft starter detects that the running current exceeds the set value of F11 during the running process.

After reaching the duration of time T, the system stops the operation of the soft-start device for over current protection and shows an over current signal on the display. If the value is set to 0, the over current protection will be disabled. Parameter MODBUS address (DEC) Setting range Default F-12: Overload protection 0x0012 0 - 4 3 Factory setting For a full description, see the user manual Parameter MODBUS address (DEC) Setting range Default F-13: Overload mode 0x0013 0 - 1 0 Factory setting If the value is set to 0, overload mode protection is active during soft start and operation of the soft start device.

If the value is set to 1, overload mode protection is active only during operation of the soft starter. Parameter MODBUS address (DEC) Setting range Default F-16: Overvoltage protection 0x0016 1000 В 480 В Factory setting If the voltage in the three-phase system is exceeded, the soft starter determines the actual voltage and compares it with the F-16 setpoint. If the F-16 value is exceeded, the soft starter will give an alarm signal. If the value is set to 0, the Overvoltage protection will be disabled. Parameter MODBUS address (DEC) Setting range Default F-17:

Undervoltage protection 0x0017 1000 В 280 В Factory setting When the voltage in the three-phase system is decreased, the soft starter determines the actual voltage and compares it with the F-17 setpoint. When the voltage value is below the setpoint in F-17, the soft starter gives an alarm signal. If the value is set to 0, the Undervoltage protection will be disabled.

VEDA MC MCD5 SOFTSTARTER Communication manual 1.1.4 Start/Stop parameters Classified as Business 4 Parameter MODBUS address (DEC) Setting range Default F-18: Output phase loss 0x0018 0 - 30 5 Factory setting If the current value (%le) in any of the phases is less than the F-18 setpoint, the soft starter will consider this as a phase loss and gives an alarm signal. If the value is set to 0, the Output phase loss protection will be disabled. Parameter MODBUS address (DEC) Setting range Default F-19: SCR Over Temperature 0x0019 0 - 90 °C 85 Factory setting If the temperature of the SCR module exceeds the value of the F-19 setpoint, the soft starter gives an alarm signal.

If the value is set to 0, the SCR Over Temperature protection will be disabled. Parameter MODBUS address (DEC) Setting range Default F-20: Timeout protection 0x0020 0 - 120с 20 с Factory setting If the soft-start time exceeds the F-20 setpoint, the soft starter gives an alarm signal. If the value is set to 0, the Timeout protection will be disabled. Parameter MODBUS address (DEC) Setting range Default F-21: lmbalanced 0x0021 0 - 100% 50% Factory setting If the difef rence between the maximum and minimum operating current reaches the F-21 setpoint (% of the rated current of the soft starter), he soft starter gives an alarm signal.

If the value is set to 0, the lmbalanced protection will be disabled. Parameter MODBUS address (DEC) Setting range Default F-00: Start Mode 0x0000 0 - 2 0 Factory setting 0: Current ramp 1: Current limit 2: Voltage ramp For a full description, see the user manual. Parameter MODBUS address (DEC) Setting range Default F-01: Soft start time 0x0001 0 - 120c 10 с Factory setting Parameter MODBUS address (DEC) Setting range Default F-02: Soft stop time 0x0002 0 - 120c 0 с Factory setting Parameter MODBUS address (DEC) Setting range Default F-03: Start-stop vollage 0x0003 20 - 75% 25% Factory setting Determines the start voltage generated by the motor when the start command is first applied.
