Change procedure
1) Set the following bits to OFF in operation command 1.
- Change command in operation disabled
- Speed change command in positioning operation
2) Set the speed change value.
3) Set the speed change command in positioning operation to ON in operation command 1.
4) Set the following bits in the operation command 1 as follows when the During operation speed change
flag in the status information turns OFF from ON.
- Set the speed change command in positioning operation to OFF.
- Set the Change command in operation disabled flag to ON.
When unintended speed changes during operation are disabled except changes by change commands
(excluding speed changes using the override function)
4. Cautions for speed change
• When the Operation Speed Change function has been used along with the Remaining Travel Distance
operation mode, if STOP command is turned ON during positioning operation, the next operation speed is
defined by the changed speed.
• The operation speed can not change in the following statuses.
- When operation is started (that is, when the START command or START input is given)
At the start of operation, change the setting of operation speed 1, operation speed 2, jog speed
zero return speed (high speed)
*1. For the jog speed and zero return speed (high speed), change the positioning parameters.
- During deceleration by STOP command
- During automatic deceleration in position control
• If an operation speed larger than the maximum speed is specified for the speed change value, a setting
error occurs and the operation speed is controlled at the maximum speed.
• To change the speed at interpolation control, the speed change value has to be set in the X-axis setting.
• The operation speed does not change during mechanical zero return (at creep). The speed change
command is ignored.
5. Program description example
In the following program, the operation speed is changed as follows.
Contents of change
X-axis Changes the operation speed to 2,000,000.
Y-axis Changes the operation speed to 2,000,000.
