Event 36: High voltage
The drive controller is interrupted:
§
The power unit is disabled and axis movement is no longer controlled by the drive controller
§
The brakes are no longer controlled by the drive controller and engage in the event of an
inactive release override (F06)
Cause
Check and action
Short delay times
Check the DC link voltage during the braking operation using the scope
image (E03) and, if necessary, reduce the delay values, use a (larger)
braking resistor or connect a DC link
Braking resistor connection
error
Check the connection to the braking resistor and supply module and
correct them if necessary
Braking resistor overloaded
Check the supply module on display
WARNING 1
; check that the
maximum permitted braking resistor power loss is suitable for the
application; replace the braking resistor if necessary
Supply voltage exceeded
Check the supply voltage for an overrun of the permitted input voltage
and adjust it if necessary

Event 37: Motor encoder
The drive controller is interrupted if:
§
U30 = 0: Inactive
Response:
§
The power unit is disabled and axis movement is no longer controlled by the drive controller
§
The brakes are no longer controlled by the drive controller and engage in the event of an
inactive release override (F06)
The drive controller is interrupted with emergency braking if:
§
U30 = 1: Active and
§
A29 = 1: Active for STOBER device controller
or
§
U30 = 1: Active and
§
A540 = 2: slow down on quick stop ramp for CiA 402 device controller
Response:
§
The axis is stopped by emergency braking; the brakes are no longer controlled by the drive
controller and engage in the event of an inactive release override (F06)
§
At the end of emergency braking, the power unit is disabled and axis movement is no longer
controlled by the drive controller
