FX3U-1PG User's Manual
b10: Zero return direction
Set the zero return direction.
b10 = 0: At the time of zero return, the operation starts toward the direction in which the current address
decreases.
b10 = 1: At the time of zero return, the operation starts toward the direction in which the current address
increases.
b11: Limit deceleration mode
Set the operation when the forward limit/reverse limit turns on.
b11 = 0: When the forward limit/reverse limit turns on, the operation immediately stops and outputs the CLR
signal.
b11 = 1: When the forward limit/reverse limit turns on, the operation decelerates and stops. The CLR signal is
not output.
b12: DOG input polarity
The polarity of the DOG input is set.
b12 = 0: Normally-opened (operates when the DOG input is on)
b12 = 1: Normally-closed (operates when the DOG input is off)
b13: Count start point
Set the count start point for zero-point signal.
b13 = 0: DOG forward end (After DOG forward end detection, the zero-point signal count starts.)
b13 = 1: DOG backward end (After DOG forward end detection and backward end finish, the zero-point signal
count starts.)
b14: STOP input polarity
The polarity of the STOP input is set. It is valid only for the input of the FX
3U-1PG STOP terminal.
b14 = 0: Normally-opened (operates when the STOP input is ON)
b14 = 1: Normally-closed (operates when the STOP input is OFF)
b15: STOP input mode
The operation for the STOP input is set.
b15 = 0: After deceleration stop by STOP command is executed during operation, the remaining distance
operation is executed when the restart command is given.
b15 = 1: After deceleration stop by STOP command is executed during operation, the positioning ends
without executing the remaining distance operation.
7.3.4 [BFM#5, #4] Maximum speed
Sets the upper speed limit in each operation.
→ For details on the maximum speed, refer to Section 6.2.
Point
• For the JOG speed, zero return speed (high speed), zero return speed (creep), operation speed I, and
operation speed II, set the speed same or lower than the maximum speed. When the set speed is higher
than the maximum speed, the operation is executed at the maximum speed.
• When the extension positioning parameter is used, use the maximum speed (BFM#39, #38).
BFM No.
