VL - Voltage Limit
Compatibility: High-voltage Stepper Drives (STAC5, STAC6 only)
Specifies the maximum voltage that will be applied to the motor by the PWM outputs on the drive.
Normally this is set to 100% for modern step motors. Some inexpensive motors are constructed with less robust
winding insulation, and require this voltage to be limited. In these rare cases, VL may be lowered. This will
directly impact motor performance, but will allow the drive to control a wider variety of motors.
