Parameter Reference D-25
AC30V series Variable Speed Drive
DC Link Volts Limit
Parameters::Motor Control::Ramp Hold
This function prevents over-voltage faults occurring due to a rapidly changing setpoint.
PNO Parameter Descriptions
1641 VDC Lim Enable
Enable DC Link Volts Limit during a fast deceleration to prevent overvoltage trip
1642 VDC Lim Level
Determines the dc link volts at which the DC Link Volts Limit sequence is started.
Entered as a percentage of the max DC link voltage (drive overvoltage level = 100%).
1643 VDC Lim Active
Set True when the deceleration ramp is paused in order to limit the DC link voltage
1644 VDC Lim Output
This diagnostic represents the speed setpoint output of the Ramp Hold Feature in Electrical Hz
