2048 pulses /rev. (2048)
[2048]
4096 pulses /rev. (4096)
[4096]
This value can also be set between 500 - 10.000 ppr.
The number of pulses per revolution can be
set between 500 - 10.000 ppr.
Function:
Set the encoder pulses per revolution on
the motor shaft.
This parameter is disabled in Open loop function.
(Parameter 100 =
SPEED OPEN LOOP
)
Description of choice:
Read the correct value from the encoder. Pay attention
to the speed limitation (rpm) for a given number of
pulses/rpm, see the drawing below:
The encoder used is a quadruple 5 volt type.
Max input frequency: 250 kHz.

341 Terminal 46, digital output
(DO 46 FUNCTION)
Value:
See table in section
Digital and relay outputs.
Function:
The output shifts from 0 V to 24 V when
the output is true.
Description of choice:
See description in section
Digital relay outputs.
342 Terminal 46, output, pulse scaling
(DO 46 MAX PULS)
Value:
1 - 50000 Hz
✭
5000 Hz
Function:
This parameter allows scaling of the pulse output signal.
Description of choice:
Set the desired value.
350 Encoder monitoring
(ENCODER MONITOR)
Value:
✭
0 (OFF)
[0]
1 (OPTION & STANDARD)
[1]
Function:
If failure on encoder lines occur selection of this
parameter can generate an alarm (alarm 44) for
avoiding unintended start of the motor.
Encoder feedback pulse/rev function is disabled in
open loop (parameter 100 =
Speed open Loop
).
Description of choice:
Select ON when the encoder cables must
be supervised.
351 Encoder direction
(ENCODER DIR.)
Value:
✭
0 (NORMAL CW)
[0]
1 (INVERSE CCW)
[1]
Function:
Change the detected encoder direction (revolution)
without changing the wires to the encoder.
Encoder monitoring function is disabled in open loop
(parameter 100 =
Speed open loop
).
Description of choice:
Select
NORMAL CW
when A channel is 90° (electrical
degrees) before channel B by clockwise rotation of
the encoder shaft. Select
INVERSE CCW
when A
channel is 90° (electrical degrees) after channel B by
counter clockwise rotation of the encoder shaft.
