Motor phse error monitoring before operation

This function extension is available from version 11.00.00!
This extended motor phase failure monitoring can both detect a phase failure on the basis
of test signals and check for the existence of the motor.
 The "motor phase error monitoring before operation" is only directly active after
controller enable if
– an error response is set in
– the motor phase error monitoring is switched on
 The following parameters show the cause of the motor phase failure:
– C00561/3: Motor phase U
– C00561/4: Motor phase V
– C00561/5: Motor phase W

Note!
The motor phase error monitoring before operation must not be connected to a
rotating or coasting machine (high compensation currents and effect of the DC
injection braking).
• In case of motor control with feedback, no motor phase error monitoring is
executed if the actual speed value is > 10 rpm.
• In case of motor control without feedback, the user must ensure that the
motor phase error monitoring will only be executed if the speed is 0.
If the motor is at quick stop and the brake is applied, no motor phase error
monitoring is executed when quick stop is deactivated (same with "0" speed and
applied brake).
If the rated current of the connected motor is lower than 10 % of the rated device
current, the motor phase error monitoring can be activated although no motor
phase error has occurred. In this case, the motor phase error monitoring must be
switched off before operation
