VM_REGEN_REACTIVE[MIN] = - VM_REGEN_REACTIVE[MAX]
Identifier VM_SPEED
Description Range applied to parameters showing speed
Units Open-loop, RFC-A, RFC-S: rpm or mm/s
Range of [MIN] Open-loop, RFC-A, RFC-S: -50000.0 to 0.0
Range of [MAX] Open-loop, RFC-A, RFC-S: 0.0 to 50000.0
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_SPEED[MIN] = 2 x VM_SPEED_FREQ_REF[MIN]
VM_SPEED[MAX] = 2 x VM_SPEED_FREQ_REF[MAX]
Identifier VM_SPEED_FREQ_KEYPAD_REF
Description Range applied to the keypad reference
Units
Open-loop: Hz
RFC-A, RFC-S: rpm or mm/s
Range of [MIN]
Open-loop: -550.0 to 550.0
RFC-A, RFC-S: -50000.0 to 50000.0
Range of [MAX]
Open-loop: 0.0 to 550.0
RFC-A, RFC-S: 0.0 to 50000.0
This variable maximum is applied to Keypad Control Mode Reference (01.017). The maximum applied to these parameters is the same as other
frequency reference parameters.
VM_SPEED_FREQ_USER_REFS [MAX] = VM_SPEED_FREQ_REF[MAX]
However the minimum is dependent on Negative Reference Clamp Enable (01.008) and Bipolar Reference Enable (01.010).

Identifier VM_SPEED_FREQ_REF
Description Range applied to the frequency or speed reference parameters
Units
Open-loop: Hz
RFC-A, RFC-S: rpm or mm/s
Range of [MIN]
Open-loop: -550.0 to 0.0
RFC-A, RFC-S: -50000.0 to 0.0
Range of [MAX]
Open-loop: 0.0 to 550.0
RFC-A, RFC-S: 0.0 to 50000.0
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.
