Signal Name
Command Pulse Input
Command sign input
• Input terminal of command pulse. The signal is received by the
high-speed photo coupler on the driver side.
• Allowable Input Highest Frequency
At the time of the line driver input : 500kpps
At the time of the open collector input
: 200kpps
• Input impedance of PULS and SIGN is 220 Ω.
• The following 3 forms of command pulse input can be selected
with Pr42 (command pulse input mode set up).
(1) 2-phase (Phase A/B) input
(2) CW (PULS)/CCW (SIGN) pulse input
(3) Command pulse (PULS)/sign (SIGN) input

The control mode can change functions.
You must not enter any command pulse for 10 ms before or after
switching.
• If you open connection with COM- when a moving part of the
machine exceeds the movable range in CW direction, no torque
will be generated in CW direction.
• If you open connection with COM- when a moving part of the
machine exceeds the movable range in CCW direction, no torque
will be generated in CCW direction.
• If you set 1 to Pr04 (Overtravel input inhibit), CWL/CCWL inputs
will be invalid. A default value is invalid (1).
• Setting of Pr66 (DB inaction during driving prohibition) can acti-
vate the dynamic brake when CWL/CCWL input is valid. Ac-
cording to a default value, the dynamic brake will run (Pr66 is 0).

Control • Input to switch dividing multiply of command
pulse
• When this signal is connected to COM-, it
will switch a command dividing multiply
numerator from Pr46 (Numerator of 1st
command pulse ratio) to Pr47 (Numerator of
2nd command pulse ratio).
<Caution>
You must not enter any command pulse for
10 ms before or after switching.

Control • With internal command speed selection 1
(INTSPD1), four-speed can be set in
combination with INTSPD 2.
