Rockwell Automation 20D PowerFlex 700S Drive Ph I Control, Frames 1...11 - Manual (Page 71)

Programming and Parameters 3-17
20 Speed Ref DPI
Sets the speed reference that the drive should use when selected in Par 16 [Speed Ref Sel].
A device communicating on a DPI port (typically a HIM) provides this value.

22 Speed Trim 2
Provides an additive speed trim value to Par 47 [Spd Trim1 SpdRef] with a Lead/Lag filter.
The Position regulator output is linked to this parameter by default. This speed trim value
affects the speed reference input to the speed regulator.

Par 4 [Motor NP RPM] = 1.0 ✓ ✓ Real
23 Speed Trim 3
Provides a scalable speed trim value that will be added to Par 47 [Spd Trim1 SpdRef]. Par 24
[SpdTrim 3 Scale] scales this value prior to the trim value affecting the speed reference.
Units:

Par 4 [Motor NP RPM] = 1.0 ✓ ✓ Real
24 SpdTrim 3 Scale
Par 23 [Speed Trim 3] is multiplied by this number. This number can be used to scale the
value of Par 23 [Speed Trim 3].
Default:
Min/Max: 1.0000
-/+1000.0000 ✓ ✓ Real
25 STrim2 Filt Gain
Sets the lead term for the Par 22 [Speed Trim 2] filter. A value greater than 1 will result in a
lead function and a value less than 1 will result in a lag function. A value of 1 will disable the
filter.
Default:
Min/Max: 1.0000
-/+15.0000 ✓ ✓ Real
26 SpdTrim2 Filt BW
Sets the frequency for the Speed Trim 2 filter.
Units:

30 Rev Speed Limit
Sets a limit on the speed reference in the negative direction. This value can be entered as a
negative value or zero.

31 Fwd Speed Limit
Sets a limit on the speed reference in the positive direction. This value can be entered as a
positive value or zero.

Par 4 [Motor NP RPM] = 1.0 ✓ Real
32 Accel Time
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]
Units:
Default:
Min/Max: Sec
10.0000
0.0100/6553.5000 ✓ ✓ Real
33 Decel Time
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]
Units:
Default:
Min/Max: Sec
10.0000

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:
Units:
Default:
Min/Max: Sec

0.0000/4.0000 ✓ ✓ Real
35 SpdRef Filt Gain
Sets the lead term for the Speed Reference filter. A value greater than 1 will result in a lead
function and a value less than 1 will result in a lag function. A value of 1 will disable the filter.
Default:
Min/Max: 1.0000
