4. Cautions
• 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 target address 1, target address 2 and, operation speed 1
and operation speed 2 before giving the START input (or command).
- During deceleration by STOP command
- During automatic deceleration in position control
• If the target position change value (address) converted in units of pulses is out of the setting range, an
error occurs.
• If the target position change value (speed) is out of the setting range, the operation speed is handled as
"1"(lower limit) or maximum speed (upper limit).
• If the specified target address requires change of the operation direction after the interrupt input changes
from OFF to ON during the following peration, the work piece moves to the address where the interrupt
input turned ON and stops there:
- Interrupt 1-speed Constant Quantity Feed
- Interrupt 2-speed Constant Quantity Feed
*1. However, the operation is different in the constant position stop mode.
• The following target address changes are not allowed during 2-speed positioning operation:
- Target address change that requires change of the operation direction at the 1st speed during 1st speed
operation
- Target address change that requires change of the target address at the 2nd speed during 1st speed
operation.
5. Program description example
