Units A
Range of [MIN] -9999.99 to 0.00
Range of [MAX] 0.00 to 9999.99
VM_DRIVE_CURRENT[MAX] is equivalent to the full scale (over current trip level) for the drive and is given by FullScaleCurrentKc (11.061).
VM_DRIVE_CURRENT[MIN] = - VM_DRIVE_CURRENT[MAX]
Identifier VM_FREQ
Description Range applied to parameters showing frequency
Units Hz
Range of [MIN] -1100.00
Range of [MAX] 1100.00
This variable minimum/maximum defines the range of speed monitoring parameters. To allow headroom for overshoot the range is set to twice the
range of the speed references.
VM_FREQ[MIN] = 2 x VM_SPEED_FREQ_REF[MIN]
VM_FREQ[MAX] = 2 x VM_SPEED_FREQ_REF[MAX]
Identifier VM_MAX_SWITCHING_FREQUENCY
Description Range applied to the maximum switching frequency parameters
Units User units
Range of [MIN] OpenLoop: 0 (0.667kHz), RFC-A: 2 (2kHz)
Range of [MAX] 8 (16kHz)
VM_SWITCHING_FREQUENCY[MAX] = Power stage dependent
VM_SWITCHING_FREQUENCY[MIN] = 0
Note that RFCA modes are not available on Unidrive M 100/101 and Commander ID drives and so these settings are not applicable on these drives.
