Functional Description
CG Drives & Automation, 01-5326-01r5
1)
= selected if only one preset reference is active
1 = active input
0 = non active input
Keyboard reference mode [369]
This parameter sets how the reference value [310] is edited.
Communication information
11.5.8 PI Speed Control [370]
The AC drive has an internal speed controller, which is used
to keep the shaft speed equal to the set speed reference. This
internal speed controller works without an external
feedback.
With the parameters speed P gain [372] and speed I time
[373] the controller can be optimized manually.
Speed PI Autotune [371]
The function speed autotune will perform a torque step
change, and measures the reaction on shaft speed.
It automatically sets the internal speed I time to its optimum
value. The speed PI autotune must be done during
operation with the motor load connected and the motor
running. “Autotune” will be flashing in the display during
the autotune operation. When the test is successfully
concluded, the display will show “Autotune OK!” for 3 s.
Communication information
NOTE: If only Preset Ctrl3 is active, then the Preset
Ref 4 can be selected. If Presets Ctrl2 and 3 are
active, then the Preset Ref 2, 4 and 6 can be selected.
