4.4.4 Details on Sequence Output Signals

This section provides information on each of sequence output signal. Pin numbers are given for indepen-
dent drive operation (M5A). Refer to the manual for the NC machine for sequence output signals and out-
put addresses.
ZSPD (Zero-speed Signal)
J
Connector number: 6CN
Pin numbers:
The ZPSD signal will turn ON when the motor speed drops to the set speed or less. Once the ZPSD
D
signal turns ON, it will be kept on hold for 50 ms.

The C1-19 (ZS
D
The ZSPD signal is output regardless of the status of the FWD or REV output. Therefore, the ZSPD
D
signal can be used as an interlock signal for hazard prevention.
AGR (Speed Agree Signal)
J
Connector number: 6CN
Pin numbers:
The AGR signal will turn ON when the motor speed reaches the range set by the SCOM signal. The
D
AGR signal will not, however, turn ON while the gate is blocked or the motor winding is selected.
Once the AGR signal turns ON, it will be kept on hold for 50 ms.
D
The AGR signal can be used in response to the S reference for NC machines in program operation to
