G5-series Linear Motors/Servo Drives With Built-in EtherCAT Communications
*2 The term “During deceleration” shows the distance until the motor decreases its speed to 30 mm/s or less from
the normal operation.
Once it decelerates to 30 mm/s or lower speed, the operation conforms to the description for “after stopping,”
regardless of the actual speed.
*3 “Immediate Stop” means that the Linear Motor stops immediately by using controls while the servo is kept ON.
The force limit at this time is controlled by the Immediate Stop Force (3511 hex) set value.
Precautions for Correct UsePrecautions for Correct Use
• An immediate stop forces the motor to decelerate quickly, which momentarily causes a large
position error in position control. This may result in an Error Counter Overflow (Error No. 24.0)
or an Overrun Limit Error (Error No. 34.0). If an error occurs, set the Following error window
(6065 hex) and the Overrun Limit Setting (3514 hex) to appropriate values.
• A Command Warning (Warning No. B1 hex) will occur if a command is given in the drive
prohibition direction while the motor is stopped (i.e., decreases the speed to approximately
30 mm/s or lower) and the Drive Prohibition Input is open.
While the Positive Drive Prohibition Input (POT) is open, the Linear Motor cannot be driven in the
positive direction, but it can be driven in the negative direction. Conversely, while the Negative
Drive Prohibition Input (NOT) is open, the Linear Motor cannot be driven in the negative
direction, but it can be driven in the positive direction.
z Immediate Stop Force (3511 hex)
This is the force limit when the Stop Selection for Drive Prohibition Input (3505 hex) is set to 2, and the
motor decelerates due to a drive prohibition input.
The settable range is 0 to 500% in units of 0.1%. When it is set to 0%, the normal force limit is used.
