Parameter Descriptions
MAX SPEED
PREF: 101.08 Default: 1500 rpm Range: 0 to 32000 rpm
The maximum speed clamp and scale factor for other speed parameters. 100% speed = maximum speed in rpm.
SPEED DEMAND
PREF: 101.09 Default: —.xx % Range: —.xx %
Indicates actual speed demand to the Drive after reference ramp.
SPEED SETPOINT
PREF: 101.10 Default: —.xx % Range: —.xx %
Indicates target speed. This will be equal to either LOCAL SETPOINT, REMOTE SETPOINT, JOG SETPOINT, COMMS

SETPOINT parameter).
REVERSE
PREF: 101.11 Default: FALSE Range: FALSE / TRUE
