3.6 If the Motor Does Not Start Up
Check the LEDs on the side of the inverter:
LED State | CombiDrive® Status | |
Green | Yellow |
|
|
|
|
ON | ON | Mains power on,CombiDrive® not running (STANDBY) |
ON | OFF | CombiDrive® running, as per control commands (ON) |
Flashing | Flashing | Current limit warning |
Flashing | ON | CombiDrive® overtemperature |
ON | Flashing | Motor overtemperature |
OFF | ON | Other fault (e.g. tripped) |
OFF | Flashing | Mains undervoltage |
OFF | OFF | Mains supply fault (e.g. faulty external switch) |
If a fault occurs: switch off, disconnect and then reconnect the power and then switch on again. Switch off if the fault condition persists. Trips can be reset by connecting a switch to(seeDIN3parameter P053).
If a warning occurs: switch off, disconnect and reconnect the power and then switch on again.
In either of the above cases, if the fault/warning persists then further investigation requires an OPm2 or a serial link connection.
3.7 Local and Remote Control
The inverter can be controlled either locally (default), or remotely via a USS data line connected to the internal RS485 telephone socket (SK200).
When local control is used (P910 = 0), the motor can only be controlled via the internal potentiometer or the control terminals. Control commands, setpoints or parameter changes received via the RS485 interface have no effect.
For remote control, the serial interface is designed as a
When operating via remote control the inverter will not accept control commands from the terminals. Exception: OFF2 or OFF3 can be activated via parameter P051 to P053 (refer to parameters P051 to P053 in section 4).
Several CombiDrive® can be connected to an external control unit at the same time and can be addressed individually.
Note: If the inverter has been set up to operate via the serial link but does not run when an ON command is received, try reversing the connections to terminals 3 and 4 on SK200.
