Subindex 2:
Motor phase failure 1: Current threshold
Monitoring 1 (in the "operation enabled" status):
Selection of the current threshold for activation
• 100 % ≡ maximum axis current (
or
for axis B)
• Background: In order to be able to reliably detect the failure of a motor phase, a certain motor current for the
current sensors must flow first. The monitoring function therefore is only activated if, in the case of a servo
control, the setpoint of the motor current, and in the case of a V/f characteristic control, the actual value of the
motor current (display in
or
for axis B) has exceeded the current threshold set here.

Subindex 3:
Motor phase failure 1: Voltage threshold
Monitoring 1 (in the "operation enabled" status):
Selection of the voltage threshold for monitoring several motor
phases
• The V/f characteristic control enables the detection of several failed motor phases during operation.
• Monitoring with regard to a failure of several motor phases is active if
• a response other than "0: No response" is set in subindex 1, and
• the motor voltage exceeds the voltage threshold set here.
• The "Motor disconnected" error message is output if the motor current is lower than the device-dependent
threshold value for more than 20 ms.
• The monitoring function for the failure of several motor phases can be deactivated if the value "1000.0 V" is set
here.
