・This is the input terminal for command pulses. The driver
receives this signal by a high-speed photo coupler.
・The input impedance of PULSE and SIGN signals is 220 Ω .
・Command pulses can be input in three different
ways. Use Pr42 to select one of the following.
① Quadrature (A and B) input
② CW (PULSE)/CCW (SIGN) pulse input
③ Command pulse (PULS)/Sign (SIGN) input
・With COM- closed, the numerator of the command
scalar is changed from the value stored in Pr46
(Numerator of 1st Command Scalar) to the value
stored in Pr47 (Numerator of 2nd Command Scalar).
< Note >
Don't enter command pulses 10 ms after
or before switching.
・Connect a backup battery for absolute
encoder (pole-sensitive !).
・If the battery is connected directly to the driver, it is
not necessary to connect a battery to this terminal.
