Attention
• When setting the speed increasing ratio to 1.00, the speed reduction ratio will
be effective.
• When setting a longer time in the “overload alarm detection time except
when holding a shaft” parameter, an overload status may continue. Repeating
this condition may result in shorter service life of the motor and gearhead.
• If a load exceeding the limited duty region was applied or output shaft was
holded, the “overload alarm detection time except when holding a shaft” is
maximum 5 seconds.
• Description of I/O signals
Assignable alternative input functions
Display Function Description
[FWd] FWD
The motor rotates when either FWD input or REV input is set to “ON”.
The motor instantaneous stop when FWD input and REV input is set to
“ON” at the same time.
[rEv] REV
[P0]
Operation data 0
These signals are used to select the operation data number. 8 speeds c
an be specified by using three opertation datas.
[P1]
Operation data 1
[P2]
Operation data 2
[A.rSt] Alarm reset
This signal is used to reset the alarm when be operated protection fun
ction.
[E.Err] External error
When turning this signal OFF, an alarm generates and the motor stops
instantaneously.
[----] Not used This input is not assigned to any signal.
Assignable alternative input functions
Display Function Description
[SPd]
Rotation speed
For every rotation of the motor, 30 pulses are output
SPEED [RPM] = (SPEED-OUT [Hz] * 60 [Sec]) / 30 [pulses]
[AL.on] Alarm output It is output when an alarm is generated (Normally closed)
[AL.ov] Over voltage alarm It is output when an alarm is finished (Nomally open)
[OvLd] Overload alarm
It is output when overload alarm is generated or exceeded
(Normally closed)
