9.4.3 Gear Ratio Changes while in Operation

 Precautions for gear ratio changes while the positioning unit is in operation
• If the gear ratio is changed with a new gear ratio while the electronic gear is in operation, the
new gear ratio will be effective with an elapse of a preset gear change time.
• If the gear ratio change time is 1, the gear ratio will be changed at an
acceleration/deceleration time of 0.
• Acceleration or deceleration during the gear ratio change results in linear acceleration or
deceleration. S-shaped acceleration or deceleration cannot be used.

 Programming method
Follow the procedure below and write a user program in the case of changing the gear ratio
while the positioning unit is in operation.
1. Gear ratio change
• Change the gear ratio numerator and denominator of the electronic gear in the setting area
for the electronic gear.
• The gear ratio at the time of starting the unit is set for this area. It is recommended to save
the initial gear ratio before change so that the initial gear ratio can be reused with ease.
1. Gear ratio change request
• Turn ON an I/O signal (electronic gear ratio change request) for the target axis allocated to
the unit.
• This signal becomes enabled by the "edge type" operation. Starts the gear ratio change
triggered by the gear ratio change request signal turned ON.
• Turn OFF the gear ratio change request signal after changing the gear ratio.
