Note: In the field-weakening range, synchronous motors can, when a fault condition exists, generate high DC link voltages.
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 * r0297/p0316 [Nm/A]
Linear motors: p1082 [m/min] <= 73.484 *r0297/0316 [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
suppressed - 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.
Description: Maximum excitation current of the induction motor referred to the permissible rated current of the power unit
(r0207[0]).
Dependency: Only effective for vector control.
Refer to: p1401, p1573
Note: The parameter is preassigned in the automatic calculation for chassis power units.
Description: Displays the operating hours for the corresponding motor.
The motor operating time counter continues to run when the pulses are enabled. When the pulse enable is
withdrawn, the counter is held and the value saved.
Dependency: The following prerequisites must be fulfilled in order to be able to save the operating hours counter in a non-volatile
fashion:
- firmware with V2.2 or higher.
- Control Unit 320 (CU320) with hardware version C or higher (module with NVRAM).
Refer to: p0651
Note: The operating hours counter in p0650 can only be reset to 0.
The operating hours counter only runs with motor data set 0 and 1 (MDS).
Description: Sets the service/maintenance intervals in hours for the appropriate motor.
An appropriate fault is output when the operating hours set here are reached.
Dependency: Refer to: p0650
