-86-
shaft gearhead using a gear
with gear ratio of 30 or 50
(200W, 400W motors)
motors), the rotating direction of
the gear output shaft is oppsite
of the motor output shaft.
Accordingly, reverse the FWD
input and REV input operations.
The rotation direction switch is
set wrong.
Check the rotation direction
switch.
The rotation speed
cannot be increased.
The speed upper limit has been
set
Raise the value of speed upper
limit parameter.
Maximum speed upper value is
4000rpm.
The rotation speed
cannot be decreased.
The speed lower limit has been
set
Lower the value of speed lower
limit parameter.
Maximum speed lower value is
50rpm.
Motor operation is unstable.
The motor (gearhead) output
shaft is not misaligned with the
load shaft.
Check the coupling condition for
The motor (gearhead) output
shaft and load shaft.
Motor vibration is too big.
Effect of electrical noise from
external device.
- Check the operation only with
the motor, drive and other
external equipment required for
operation. If an effect of noise
has been confirmed, implement
the following countermeasures.
- Move the unit farther away
from the noise generation
sources.
- Reviewing the wiring.
- Change the signal cables to a
shielded type.
- Install ferrite cores.
