If ForceReferenceDirection (01.057) = 0 then it has no effect. If ForceReferenceDirection (01.057) is non-zero then the modulus of the reference is used and
the sign is defined by the value of ForceReferenceDirection (01.057). If ForceReferenceDirection (01.057) = 1 then Pre-skipFilterReference (01.002) is
always positive, and if ForceReferenceDirection (01.057) = 2 then Pre-skipFilterReference (01.002) is always zero or negative.
Parameter 01.069 Reference in rpm
Short description Displays the value of the reference in rpm
Mode Open‑loop
Minimum -33000 Maximum 33000
Default Units rpm

Referenceinrpm (01.069) = Pre-rampReference (01.003) x 60 / Pole Pairs (see NumberOfMotorPoles (05.011)).
Parameter 01.070 Clamped Reference
Short description Displays the reference that is provided for the PID controller
Mode Open‑loop
Minimum −VM_SPEED_FREQ_REF Maximum VM_SPEED_FREQ_REF
Default Units Hz

The ClampedReference (01.070) is provided as a source for various drive user functions.
Parameter 01.071 Alternative Reference
Short description Defines the reference which is used as a destination for the output of the PID controller
Mode Open‑loop
Minimum −VM_SPEED_FREQ_REF Maximum VM_SPEED_FREQ_REF
Default 0.00 Units Hz

AlternativeReference (01.071) is provided as a destination for an alternative reference if required (such as a drive user function output).
If AlternativeReference (01.071) has been programmed as a destination, AlternativeReferenceEnable (01.072) is set to 1 automatically so that the alternative
reference is selected.
Parameter 01.072 Alternative Reference Enable
Short description Indicates when the Alternative Reference is being used
Mode Open‑loop
Minimum 0 Maximum 1
