Error message
Various monitoring functions protect the drive against impermissible operating
conditions. If a monitoring function is activated, a response corresponding to the
protection of the drive is actuated. The following things are monitored:
ƒ
Temperature of the output stage
ƒ
Motor temperature
ƒ
I2t monitoring of the motor
ƒ
Overcurrent / short circuit of the output stage
ƒ
DC−bus voltage (under− and overvoltage)
ƒ
Following error with regard to position control
ƒ
Error with regard to the reference run
ƒ
Error with regard to the angle encoder system
ƒ
Communication error
ƒ
Initialisation error
ƒ
Check sum error of the parameters
Some responses to failures can be set within the SDC parameterisation software. Possible
responses are:
Reaction
Meaning
Reaction of the drive
A
Immediate disconnection of the
output stage
The motor coasts.
h
Emergency stop
The motor is braked to zero speed at the current limit. If there
is a motor holding brake, it is applied. The output stage
switches off.
W
Warning
The controller keeps operating, the output stage remains
switched on. The warning signal can be read out via the CAN
bus or via the serial RS232 interface.
O
