Speed Ref A Sel
Speed Ref B Sel
Selects the speed reference source for the drive. The selected speed reference values converge in the final
selection of the drives speed reference with
Par 152 [Applied LogicCmd] and are selected with bits 28, 29, 30.
See the Block Diagrams beginning on page 173 for a description.

29 Jog Speed 1
Sets the speed reference that the drive should use when responding to bit 18 [Jog 1] of
Par 152 [Applied LogicCmd].
Default:
Min/Max:
Units:
Scale: 0.0000
-/+8.0000 P.U.

30 Min Spd Ref Lim
Sets the minimum speed reference limit. This value may be negative or positive but not greater than
Par 31 [Max Spd Ref Lim].
Default:

31 Max Spd Ref Lim
Sets the maximum speed reference limit. This value may be negative or positive but not less than
Par 30 [Min Spd Ref Lim].
Default:
Min/Max:

Scale: 0.0000
Par 30 [Min Spd Ref Lim]/8.0000
rpm
Par 4 [Motor NP RPM] = 1.0 P.U.

32 Accel Time 1
Sets the rate of acceleration for all speed increases, with time in seconds to base speed.
Accel Rate =
Par 4 [Motor NP RPM] / Par 32 [Accel Time]
Default:
Min/Max:
Units: 10.0000
0.0100/6553.5000
s Y RW Real
33 Decel Time 1
Sets the rate of deceleration for all speed decreases, with time in seconds to base speed.
Decel Rate =
Par 4 [Motor NP RPM] / Par 33 [Decel Time]
Default:
Min/Max:
Units: 10.0000
0.0100/6553.5000
s Y RW Real
34 S Curve Time
Sets the S time (Round In and Round Out ) in seconds. Half of the time specified is added to the beginning and
half to the end of the applied ramp. The S time is independent of speed and results in a trapezoidal torque profile.
For example:
Default:
Min/Max:
Units: 0.5000
0.0000/4.0000
s Y RW Real
35 SpdRef Filt Gain
Sets the lead term for the Speed Reference filter. Values greater than 1 will result in a lead function and values
less than 1 will result in a lag function. A value of 1 will disable the filter.
Default:
Min/Max: 1.0000
-/+5.0000 Y RW Real
36 SpdRef Filt BW

37 Spd Ref Bypass
The speed command after the limit, ramp and s-curve blocks. Link a source directly to this parameter to bypass
these blocks.
Default:
