3 BASIC FUNCTION
3.4 Stroke limit function [G] [WG]
Stop method at stroke limit detection
When LSP (Forward rotation stroke end)/LSN (Reverse rotation stroke end) or FLS (Upper stroke limit)/RLS (Lower stroke
limit) is turned off, the servo motor stops with the stop method shown in this section.
In the cyclic synchronous position mode (csp), stop the command when the stroke end is detected. When the command
position exceeds the position where the stroke end is detected by 30 bits, [AL. 069 Command error] occurs. If [AL. 069
Command error] occurs, the home position is erased. Perform homing again.
Page 42 Homing mode (hm) and homing
When the stroke limit signal is detected, perform the following return methods.
Operation status
Remark
During rotation at constant speed
During deceleration to a stop
The servo motor stops after having
traveled for the droop pulses.
Perform homing again.
Control mode
Return method
Cyclic synchronous position mode
After following up [Target position (Obj. 607Ah)] with [Position actual value (Obj. 6061h)], input the position
command of the direction opposite to the limit.
Make sure that Bit 12 of [Statusword (Obj. 6041h)] is 0 before inputting the position command.
Cyclic synchronous velocity mode
Input the speed command of the direction opposite to the limit to [Target velocity (Obj. 60FFh)].
Make sure that Bit 12 of [Statusword (Obj. 6041h)] is 0 before inputting the speed command.
Profile position mode
Input the position command of the direction opposite to the limit to [Target position (Obj. 607Ah)].
Profile velocity mode
Input the speed command of the direction opposite to the limit to [Target velocity (Obj. 60FFh)].
