Programming
Description of choice:
If [1] Locked is selected, data changes cannot be made.

Operating state at power up, local control
Value:

3
Auto restart, use saved ref. (AUTO RESTART)
Forced stop, use saved ref. (LOCAL=STOP)
Forced stop, set ref. to 0 (LOCAL=STOP, REF=0)
Function:
Setting of the desired operating mode when the mains
voltage is reconnected.
This function can only be active in connection with [1]
Local control in parameter 002.
Description of choice:
[0] Auto restart, use saved ref. is selected if the unit is to
start up with the same local reference (set in parameter
003) and the same start/stop conditions (given via the
[Start/Stop] keys) that the FC motor had before it was
switched off.
[1] Forced stop, use saved ref. is used if the unit is to remain
stopped when the mains voltage is connected, until the
[START] key is pressed. After the start command, the local
reference used is set in parameter 003.
[2] Forced stop, set ref. to 0 is selected if the unit is to
remain stopped when the mains voltage is connected.
Local reference (parameter 003) is reset.
3.2.1 Parameter Group 1-** Load/Motor
100
Configuration
Value:
Speed, open loop mode (SPEED OPEN LOOP)
Process, closed loop mode
(PROCESS CLOSED LOOP)
Function:
This parameter is used for selecting the configuration to
which the FC motor is to be adapted.
Description of choice:
If [0] Speed, open loop mode is selected, a normal speed
control (without feedback signal) is obtained, but with
automatic slip compensation, ensuring a nearly constant
speed at varying loads. Compensations are active, but may
be disabled as required in parameter 133 - 136.
If [3] Process, closed loop mode is selected, the internal
process regulator will be activated, thereby enabling
accurate regulation of a process with respect to a given
process signal. The process signal can be set using the
actual process unit or as a percentage. A feedback signal
must be supplied from the process, and the process
setpoint must be adjusted. In process closed loop both
directions is not allowed in parameter 200.
101
Torque characteristics
Value:
Constant torque (CONSTANT TORQUE)
40
®
VLT
DriveMotor FCM Series
Variable torque: low (VAR.TORQUE: LOW)
Var. torque: medium (VAR.TORQUE: MEDIUM)
Variable torque: high (VAR.TORQUE: HIGH)
Function:
In this parameter, the principle for adjusting the U/f
[0]
characteristics of the FC motor to the torque characteristics
[1]
of the load is selected.
[2]
Description of choice:
If [1] Constant torque is selected, a load-dependent U/f
characteristic is obtained in which the output voltage is
increased in the case of an increasing load (current) so as
to maintain constant magnetisation of the motor.
Select [2] Variable torque low, [3] Variable torque medium or
[4] Variable torque high if the load is square (centrifugal
pumps, fans).
