2 Parameters
2.2 List of parameters
Description: Sets the current limit.
Dependency: Refer to: r0209, p0323
Note: The parameter is part of the quick commissioning (p0010 = 1); this means that it is appropriately pre-assigned when
changing p0305, p0323 and p0338.
The current limit p0640 is limited to r0209 and p0323. The limit to p0323 is not realized if a value of zero is entered
there.
The resulting current limit is displayed in r0067 and if required, r0067 is reduced by the thermal model of the Motor
Module.
The torque and power limits (p1520, p1521, p1530, p1531) matching the current limit are automatically calculated
when exiting the quick commissioning using p3900 > 0 or using the automatic parameterization with p0340 = 3, 5.
For VECTOR the following applies (p0107):
p0640 is limited to 4.0 x p0305.
p0640 is pre-assigned for the automatic self commissioning routine (e.g. to 1.5 x p0305, with p0305 = r0207[1]).
p0640 must be entered when commissioning the system. This is the reason that p0640 is not calculated by the
automatic parameterization when exiting the quick commissioning (p3900 > 0).
For SERVO the following applies (p0107):
p0640 is pre-assigned as follows using the automatic parameterization (p0340 = 1, p3900 > 0) taking into account
the limits r0209 and r0323:
- for induction motors: p0640 = 1.5 x p0305
- for synchronous motors: p0640 = p0338
Description: Sets the signal source for scaling the current limit (p0640).
Description: Sets the overvoltage protection for synchronous motors in the field-weakening range.
Value: 0: No measure
1: Voltage Protection Module (VPM)
Dependency: Refer to: p0316, p1082, p1231, p9601, p9801
Refer to: 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 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.
