• You can switch the numerator of electronic gear.
• By connecting to COM–, you can switch the numerator of
electronic gear from Pr48 (1st numerator of electronic
gear) to Pr49 (2nd numerator of electronic gear)
• For the selection of command division/multiplication, refer
to the table of next page, "Numerator selection of
command scaling"
• Input of internal speed selection 3 (INTSPD3).
•
You can make up to 8-speed setups combining INH/
INTSPD1 and CL/INTSPD2 inputs. For details of setup,
refer to the table of P.131, "Selection of Internal Speed".

• Turns to Servo-ON status by connecting this input to COM–.
• Turns to Servo-OFF status by opening connection to COM–, and current
to the motor will be shut off.
• You can select the dynamic brake action and the deviation counter
clearing action at Servo-OFF with Pr69 (Sequence at Servo-OFF).
<Caution>
1.Servo-ON input becomes valid approx. 2 sec after power-on.
(see P.42, "Timing Chart" of Preparation.)
2.Never run/stop the motor with Servo-ON/OFF.
3.After shifting to Servo-ON, allow 100ms or longer pause before entering
the pulse command.
