100 Configuration
(CONFIG. MODE)
Value:
✭
Speed, open loop mode (SPEED OPEN LOOP)
[0]
Process, closed loop mode
(PROCESS CLOSED LOOP)
[1]
Function:
This parameter is used for selecting the configuration
to which the FC motor is to be adapted.
Description of choice:
If
Speed, open loop mode
[0] 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
Process, closed loop mode
[3] 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.
NB!:
This is only possible in Stop Mode (motor
stopped on a Stop command).
101 Torque characteristics
(TORQUE CHARACT)
Value:
✭
Constant torque (CONSTANT TORQUE)
[1]
Variable torque: low (VAR.TORQUE: LOW)
[2]
Var. torque: medium (VAR.TORQUE: MEDIUM)
[3]
Variable torque: high (VAR.TORQUE: HIGH)
[4]
Function:
In this parameter, the principle for adjusting the
U/f characteristics of the FC motor to the torque
characteristics of the load is selected.
Description of choice:
If
Constant torque
[1] 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
Variable torque low
[2],
Variable torque
medium
[3] or
Variable torque high
[4] if the load
is square (centrifugal pumps, fans).
NB!:
Slip compensation (parameter 136) and
start (parameter 134) are not active if a
variable torque is used.
102 Motor power
(MOTOR POWER)
Value:
XX.XX kW - depends on the FC motor
[XXXX]
Function:
Read only parameter.
103 Motor voltage
(MOTOR VOLTAGE)
Value:
XX V- depends on the FC motor
[XX]
Function:
Read only parameter.
104 Motor frequency
(MOTOR FREQUENCY)
Value:
XX.X Hz - depends on the FC motor
[XXX]
Function:
Read only parameter.
