Emerson unidrive m200 - Electrical Installation; SI-Ethernet Module Overview and Connections

Identifier VM_POSITIVE_REF_CLAMP
Description Limits applied to the positive frequency reference 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 clamps, MaximumReferenceClamp (01.006) and M2Maximum
ReferenceClamp (21.001) , which in turn limits the references.
Note - Parameter 11.045 is not available on M100/M101 and so only the Motor 1 parameter is relevant.
This values are model dependent. See the table below.
Models Clamp level
M100 - M400 550.00
Commander ID 150.00
Identifier VM_POWER
Description Range applied to parameters that either set or display 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 a.c. output
voltage, at maximum controlled current and unity power factor.
VM_POWER[MAX] = √3 x VM_AC_VOLTAGE[MAX] x VM_DRIVE_CURRENT[MAX] / 1000
VM_POWER[MIN] = -VM_POWER[MAX]
Identifier VM_RATED_CURRENT
Description Range applied to rated current parameters
Units A
Range of [MIN] 0.00
Range of [MAX] 0.00 to 9999.99
VM_RATED_CURRENT [MAX] = MaximumRatedCurrent (11.060) and is dependent on the drive rating.
VM_RATED_CURRENT [MIN] = 0.00
Identifier VM_SPEED_FREQ_REF
Description Range applied to the frequency reference parameters
Units Hz
Range of [MIN] -550.00 to 0.00
Range of [MAX] 0.00 to 550.00
This variable minimum/maximum is applied throughout the frequency and speed reference system so that the references can vary in the range from the
minimum to maximum clamps.
