5.1 Initialization method for phase

• Set the initialization method for the phase in A670.
A670=0: When the phase initialization signal (input terminal function 188/189) is turned ON from OFF, the current
phase is initialized to A671.
A670=1: When the Z phase of the encoder option is input, the current phase is initialized to A671.
(Caution)
• When A675 > A676 (the gear ratio of the machine is less than 1), do not use A670=1. (The current phase cannot be
specified uniquely)
• When A670=1, input the encoder Z phase signal.
