8.3 Electronic Gear Function8-98.3.3 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, thenew 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 anacceleration/deceleration time of 0.• Acceleration or deceleration during the gear ratio change results in linear acceleration ordeceleration. S-shaped acceleration or deceleration cannot be used.Speed [V] Gear ratio change time(1 ms)Gear ratio change time(100 ms)Gear ratio change request signalGear ratio numerator/Gear ratio denominator 200 ／ 1001 10050 ／ 100100 ／ 100Gear ratio change timeInput speedOutput speedTime [T] ProgrammingFollow the procedure below and write a user program in the case of changing the gear ratiowhile the positioning unit is in operation.1. Change the gear ratio.Change the gear ratio numerator and denominator of the electronic gear in the setting area forthe electronic gear.The gear ratio at the time of starting the positioning unit is set for this area. It is recommendedto save the initial gear ratio before change so that the initial gear ratio can be reused withease.2. Turn ON the gear ratio change request contact.Turn ON an I/O signal (electronic gear ratio change request) for the target axis allocated tothe unit.This signal enabled is of edge type. Starts the gear ratio change triggered by the gear ratiochange request signal turned ON.
