VM_MOTOR2_CURRENT_LIMIT
Units %
Range of [MIN] 0.0
Range of [MAX] 0.0 to 1000.0
VM_MOTOR2_CURRENT_LIMIT[MAX] is dependent on the drive rating and motor set-up parameters.
VM_MOTOR2_CURRENT_LIMIT[MIN] = 0.0
Definition
Refer to VM_MOTOR1_CURRENT_LIMIT for more information. For VM_MOTOR2_CURRENT_LIMIT[MAX] use
Pr 21.007 instead of Pr 05.007 and Pr 21.010 instead of Pr 05.010.
VM_NEGATIVE_REF_CLAMP1
Units Hz
Range of [MIN] -550.00 to 0.00
Range of [MAX] 0.00 to 550.00
This variable maximum/minimum defines the range of the negative frequency clamp associated with motor map 1
(Minimum Speed (01.007)). The minimum and maximum are affected by the settings of the Negative Reference Clamp
Enable (01.008), Bipolar Reference Enable (01.010) and Maximum Speed (01.006) as shown in the table below.

VM_NEGATIVE_REF_CLAMP2
Units Hz
Range of [MIN] -550.00 to 0.00
Range of [MAX] 0.00 to 550.00
This variable maximum/minimum defines the range of the negative frequency clamp associated with motor map 2 (M2
Definition Minimum Speed (21.002)). It is defined in the same way as VM_NEGATIVE_REF_CLAMP1 except that the M2
Maximum Speed (21.001) is used instead of Maximum Speed (01.006).
VM_POSITIVE_REF_CLAMP
Units Hz
Range of [MIN] 0.00
Range of [MAX] 550.00
VM_POSITIVE_REF_CLAMP[MAX] defines the range of the positive reference clamp, Maximum Speed (01.006),
Definition
which in turn limit the references.
VM_POWER
Units kW
Range of [MIN] -9999.99 to 0.00
Range of [MAX] 0.00 to 9999.99
VM_POWER[MAX] is rating dependent and is chosen to allow for the maximum power that can be output by the drive
with maximum AC output voltage, at maximum controlled current and unity power factor.
Definition
VM_POWER[MAX] = 3 x VM_AC_VOLTAGE[MAX] x VM_DRIVE_CURRENT[MAX] / 1000
VM_POWER[MIN] = -VM_POWER[MAX]
