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 or
FIREWIRE SETPOINT before reference ramp. (Refer to the REFERENCE JOG function block for the JOG SETPOINT parameter).
REVERSE PREF: 101.11 Default: FALSE Range: FALSE / TRUE
Indicates demanded direction. This may not be the actual direction as no account of setpoint sign is taken.
LOCAL SETPOINT PREF: 101.12 Default: —.xx % Range: —.xx %
Indicates the Keypad setpoint. It is always a positive quantity; saved on power down. Direction is taken from LOCAL REVERSE.
LOCAL REVERSE PREF: 101.13 Default: FALSE Range: FALSE / TRUE
Indicates demanded direction in Local Reference mode, saved on power down.
COMMS SETPOINT
PREF: 101.14 Default: 0.00 % Range: -300.00 to 300.00 %
This setpoint is the target reference that the Drive will ramp to in Remote Reference Comms mode (not including trim). A positive value indicates a
forward direction.
FWIRE SETPOINT PREF: 101.15 Default: —.xx % Range: —.xx %
This diagnostic shows the Firewire Ref speed setpoint.
SPEED DEMAND PREF: 101.16 Default: —.x Hz Range: —.x Hz
Indicates actual speed demand to the Drive after reference ramp.
