VM_DC_VOLTAGE_SET
Units V
Range of [MIN] 0
Range of [MAX] 0 to 1150
VM_DC_VOLTAGE_SET[MAX] is drive voltage rating dependent. See Table 10-4
Definition
VM_DC_VOLTAGE_SET[MIN] = 0
VM_DRIVE_CURRENT
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 Full
Scale Current Kc (11.061).
Definition
VM_DRIVE_CURRENT[MIN] = - VM_DRIVE_CURRENT[MAX]
VM_FREQ
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.
Definition
VM_FREQ[MIN] = 2 x VM_SPEED_FREQ_REF[MIN]
VM_FREQ[MAX] = 2 x VM_SPEED_FREQ_REF[MAX]
VM_MAX_SWITCHING_FREQUENCY
Units User units
Range of [MIN] Open-loop: 0 (0.667 kHz)
Range of [MAX] Open-loop: 8 (16kHz)
VM_SWITCHING_FREQUENCY[MAX] = Power stage dependent
VM_SWITCHING_FREQUENCY[MIN] = 0
This variable maximum is used by the Minimum Switching Frequency (05.038) to define the minimum frequency limit
used if the inverter thermal model is actively reducing the switching frequency due to temperature.
Definition
Note that parameter Maximum Switching Frequency (05.018) takes priority over parameter Minimum Switching
Frequency (05.038) so is not limited by parameter Minimum Switching Frequency (05.038). The actual minimum
switching frequency limit used is the lower of Maximum Switching Frequency (05.018) and Minimum Switching
Frequency (05.038).
