VLT
®
5000 Series
Description of choice:
See description of parameter 319.
Connections - see the below drawing.
327
327 Pulse reference, max. frequency
(PULSE REF MAX)
Value:
100 - 65000 Hz at terminal 29
100 - 5000 Hz at terminal 17
✭ 5000 Hz
Function:
In this parameter, the signal value is set that corre-
sponds to the maximum reference value set in
parameter 205.
Description of choice:
Set the desired pulse reference.
328
328 Pulse feedback, max. frequency
(PULSE FEEDB MAX)
Value:
100 - 65000 Hz at terminal 33
✭ 25000 Hz
Function:
This is where to set the feedback value that is to
correspond to the maximum feed back value.
Description of choice:
Set the desired feedback value.
329
329 Encoder feedback pulse/rev.
(ENCODER PULSES)
Value:
128 pulses /rev. (128)
[128]
256 pulses /rev. (256)
[256]
512 pulses /rev. (512)
[512]
✭1024 pulses /rev. (1024)
[1024]
2048 pulses /rev. (2048)
[2048]
4096 pulses /rev. (4096)
[4096]
✭ This value can also be set between 1-4096
pulses/rev.
Function:
This is where to set the encoder pulses per revolu-
tion that correspond to the motor rpm.
This parameter is only available in
Speed control,
closed loop and in Torque control, speed feedback
(parameter 100).
Description of choice:
Read the correct value from the encoder. Pay atten-
tion to the speed limitation (rpm) for a given number
of pulses/rpm, see the drawing below:
The encoder used is to be of the Open Collector
PNP 0/24 V DC type (max. 20 kHz) or a Push-Pull
circuit 0/24 V DC (max. 65 kHz).
330
330 Freeze reference/output function
(FREEZE REF/OUTP.)
Value:
✭No operation (NO OPERATION)
[0]
Freeze reference (FREEZE REFERENCE)
[1]
Freeze output (FREEZE OUTPUT)
[2]
Function:
In this parameter it is possible to freeze either the
reference or the output.
Description of choice:
Freeze reference [1] freezes the actual reference.
The frozen reference is now the basis for Speed up
and Speed down.
Freeze output [2] freezes the actual motor frequency
(Hz). The frozen frequency is now the basis for
Speed up and Speed down.
NB!:
If Freeze output is active, the frequency con-
verter cannot be stopped via terminals 18 and
19, but only via terminal 27 (to be programmed for
Coasting stop, inverse [0] or Reset and coasting
stop, inverse [1]).
