The automatic identification is activated by setting this parameter to the appropriate
value followed by a start command in the requested direction. The start command to the
drive has to be given within 20 s. If no start command is given within 20 s the identifi-
cation run is cancelled and the parameter will be reset to its default setting. The iden-
tification run can be stopped any time with normal stop command and the parameter is
reset to its default setting. In case identification run detects fault or other problems, the
identification run is completed if possible. After the identification is finished, the applica-
tion checks the status of the identification and generates fault/ warning if any.
During Identification Run, the brake control is disabled (see chapter Error! Reference
source not found.).
3 = Encoder identification run
For PMS motor drive will make angle identification run when absolute encoder is in use.
4 = No Action
5 = Identification failed
633 CL: Start-up torque, forward
(2.5.18.12)
Sets the start-up torque for forward direction if selected with par. ID621.
634 CL: Start-up torque, reverse
(2.5.18.13)
Sets the start-up torque for reverse direction if selected with par. ID621.
636 Minimum frequency for Open Loop torque control
(2.8.8)
Defines the frequency limit below which the frequency converter operates in
frequency
control mode
.
Because of the nominal slip of the motor, the internal torque calculation is inaccurate at
low speeds where is it recommended to use the frequency control mode.
637 Speed controller P gain, Open Loop
(2.5.13)
Defines the P gain for the speed controlled in Open Loop control mode.
638 Speed controller I gain, Open Loop
(2.5.14)
Defines the I gain for the speed controlled in Open Loop control mode.
639 Torque controller P gain
(2.8.9)
Defines the P gain of the torque controller.
640 Torque controller I gain (
2.8.10)
Defines the I gain of the torque controller.
