Under Home return Operation (GHMS) PLC input signal
When the “HOME” signal is turned “ON”, this command is processed at the startup (ON edge), and the
home return operation is performed automatically. During the home return operation, the “GHMS” signal is
turned “ON”.
When the “HEND” signal is turned “ON”, turn “OFF” the “HOME” signal.
Once the “HEND” signal is turned “ON”, it can not be turned “OFF” until the power is turned “OFF” or the
“HOME” signal is input again. Once the HEND signal is turned ON, it can not be turned OFF until the power
is turned OFF or the HOME signal is input again.
Even after the completion of the home return operation, when the “HOME” signal is turned “ON”, the home
return operation can be performed.
Caution: In the Remote I/O Modes 1 to 3 and Position/Simplified Direct Value Modes 1 and 2, when the
positioning command is issued without performing the home return operation after the power
injection, the positioning is performed after the automatic home return operation.
Exercise caution that in the Half Direct Modes 1 to 3 or Full Direct Mode, issuing a positioning
command to a given position following the power on, without performing a home return first, will
generate an alarm “Error Code 83: ALARM HOME ABS (absolute position move command
when home return is not yet completed)” (operation-reset alarm).
