VH[N], VL[N] - High and Low Reference Limit

Purpose:
Define the drive’s minimum and maximum speed and position reference limits.
Software commands beyond these values are not accepted, and are truncated to VL[N]
and VH[N].

The reference to the speed controller is limited to the [VL[2]…VH[2]] range.
The reference to the position controller is limited to the [VL[3]…VH[3]] range.

Restrictions: MO=0

VH[N] > VL[N] for all entries

Default values:

VH[2]=15,000,000, VH[3]= 999,999,990

VL[2]=-15,000,000,

VL[3]=-999,999,990

Unit modes:

VH[3], VL[3]: UM=3, 4, 5

Activation: Immediate
SimplIQ: Similar

Notes:

• In position modes (UM=4, 5) motor movement is enabled in both directions within

the defined position reference range. If feedback has been extended beyond those
limits, the motor can be enabled by the user (MO=1) but the motion can only be in
the direction towards the reference limit range.

• VH[2] is used to determine the maximum and minimum allowed speed for the

PWM reference generator in 50% and 100% PWM modes.
