11.7.4 Motion Command Operation for External Latches with DC Power Input Σ-V-
series SERVOPACKs
If you use an external latch signal (/EXT1) with a DC Power Input Σ-V-series SERVOPACK, always change the setting
of the Input Signal Selection 5 in the Pn511 SERVOPACK parameter so that /EXT1 is used. This signal is disabled in
the default settings.
If you attempt to execute a motion command
*2 using /EXT1 *1 when /EXT1 is disabled, a Set Parameter Error warning
(Monitoring Parameter IL 02, bit 1) will occur and execution of the motion command will end in an error.
* 1. Set bits 0 to 3 (Latch Detection Signal Selection) or bits 4 to 7 (External Positioning Signal Setting) of Setting
Parameter OW 04 to 3 (/EXT1) or set Setting Parameter OW 3C (Zero Point Return Method) to 1 (ZERO), 2
(DEC1 + ZERO), 14 (Home LS & C Pulse), or 15 (Home Only).
* 2. Set Setting Parameter OW 08 (Interpolation Mode with Latch Input) to 2 (EX_POSING (External Positioning)),
6 (LATCH), or 9 (ZSET) Set Zero Point)).
