Description: Sets the overvoltage protection for synchronous motors in the field-weakening range.
Values: 0: No measure
1: Voltage Protection Module (VPM)
Dependency: Refer to: p0316, p1082, p1231, p9601, p9801
Refer to: F07432, F07906, F07907
Notice: When the speed limiting is removed, the user is responsible for implementing a suitable overvoltage protection.
Note: In the field-weakening range, synchronous motors can, when a fault condition exists, generate high DC link volt-
ages. The following possibilities exist to protect the drive system from being destroyed due to overvoltage:
- limit the maximum speed (p1082) without any additional protection.
The maximum speed without protection is calculated as follows:
Rotary motors: p1082 [rpm] <= 11.695 * p0297/p0316 [Nm/A]
Linear motors: p1082 [m/min] <= 73.484 *p0297/0316 [N/A]
- use a Voltage Protection Module (VPM) in conjunction with the function "Safe Torque Off" (p9601, p9801).
When a fault condition exists, the VPM short-circuits the motors. During the short-circuit, the pulses must be can-
celed - this means that the terminals for the function "Safe Torque Off" must be connected to the VPM.
- activating the internal voltage protection (IVP) with p1231 = 3.
