P3.1.4.13.4 TORQUE STABILATOR DAMPING TIME CONSTANT FOR PMM (ID 1735)
The damping time constant of the torque stabiliser for PM motors (Permanent Magnet
motors).
9.2 START/STOP SETUP
You must give the start and stop commands differently in each control place.
REMOTE CONTROL PLACE (I/O A)
Use the parameters P3.5.1.1 (Control signal 1 A), P3.5.1.2 (Control signal 2 A) and P3.5.1.3
(Control signal 3 A) to make a selection of digital inputs. These digital inputs control the
start, stop and reverse commands. Then make a selection of a logic for these inputs with
P3.2.6 I/O A Logic.
REMOTE CONTROL PLACE (I/O B)
Use the parameters P3.5.1.4 (Control signal 1 B), P3.5.1.5 (Control signal 2 B) and P3.5.1.6
(Control signal 3 B) to make a selection of digital inputs. These digital inputs control the
start, stop and reverse commands. Then make a selection of a logic for these inputs with
P3.2.7 I/O B Logic.
LOCAL CONTROL PLACE (KEYPAD)
The start and stop commands come from the keypad buttons. The direction of the rotation is
set with parameter P3.3.1.9 Keypad direction.
REMOTE CONTROL PLACE (FIELDBUS)
Start, stop and reverse commands come from the fieldbus.
P3.2.5 STOP FUNCTION (ID 506)
Table 116:
Selection
number
Selection name Description
0 Coasting
The motor stops on its inertia. When the stop command is
given, the control by the drive stops and the current from the
drive goes to 0.
1 Ramp
After the stop command, the speed of the motor is decreased
to zero speed according to the deceleration parameters.
P3.2.6 I/O A START/STOP LOGIC (ID 300)
It is possible to control the start and stop of the drive with the digital signals in this
parameter.
The selections that include the word edge help you to prevent an accidental start.
