Remedy:
• Use supply module 934X or
• Use (additional)brake choppers type 935X
When several controllers are operated simultaneously, an operation as DC bus connection may be
useful.
Here, the generated brake energy of one drive can serve as drive energy for another drive.
The mains connections only supply the energy difference.
2.13.13.3EarthFault(monitoringforearthfaultOC2)
• This function protects the drive controller.
• The message is triggered by MCTRL_bEarthFault_b =TRUE.
Function
The controllers of the 93XX series are equipped with an earth fault detection as a standard.
If the monitoring is triggered, the drive controller must be disconnected from the mains power and
the earth fault must be removed.
Features:
• LECOM no.: 12
• Reaction: TRIP (cannot be modified)
Possible earth fault causes:
• Short-circuit to frame of the machine
• Short-circuit of a phase to the screen
• Short-circuit of a phase to PE
2.13.13.4 ShortCircuit (monitoring for a short-circuit OC1)
• This function protects the drive controller.
• The message is triggered by MCTRL_bShortCiruit_b =TRUE.
Function
This monitoring is triggered by ashort-circuit of the motor phases. It can also bea short-circuit of the
windings in the machine.
This monitoring however, also reacts during mains connection (power-on), if there is an Earth fault
present.
If the monitoring is triggered, the drive controller must be disconnected from the mains power and
the earth fault must be removed.
Features:
• LECOM no.: 11
• Reaction: TRIP (cannot be modified)
