Programming
100 Configuration
(CONFIG. MODE)
Value:
Speed control, open loop (SPEED OPEN LOOP)
[0]
✭
Speed control, closed loop
(SPEED CLOSED LOOP) [1]
Torque control, speed feedback
(TORQUE CONTROL SPEED) [5]
Function:
This parameter is used for selecting the configuration
to which the frequency converter is to be adapted.
This makes adaptation to a given application simple,
because the parameters that are not used in the
given configuration are covered up (not active).
By changing between the different application
configurations, bumpless transfer is ensured.
Description of choice:
If Speed control, open loop [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 the
‘Load and motor ’ parameter group.
If Speed control, closed loop [1] is selected, a full
holding torque is obtained at 0 rpm, in addition to
increased speed accuracy. A feedback signal must be
provided and the speed PID regulator must be set.
If Torque control, speed feedback [5] is selected,
an encoder speed feedback signal must be
connected to the encoder input.
Switching between open loop and closed
loop can only happen when a stop
command has been applied.
101 Torque characteristics
(TORQUE CHARACT)
Value:
✭
High-constant torque (H-CONSTANT TORQUE)
[1]
Normal-constant torque
(N-CONSTANT TORQUE) [11]
Function:
Selecting of torque characteristics.
Description of choice:
By VLT 5000 Flux it is possible to select High-Constant
Torqueor Normal-constant torque .

Depends on the unit
Function:
Selects the kW value that corresponds to the
rated power of the motor.
A rated kW value has been selected as the factory
setting that corresponds to the unit size.
Description of choice:
Select a value that equals the nameplate data on the
motor. There are 4 possible undersizes or 1 oversize
in comparison with the factory setting.
Also, alternatively it is possible to set the value for
motor power as an infinitely variable value.
The set value automatically changes the values of the
motor parameters in parameter 150-154, 157 and 161.
