Revision Jan. 2007, MDE2, SW V1.05 5-27
When this parameter is NOT set to 00 “No limit signal” and Pr. 0-17 is NOT set to 0, it will be
regarded as open/close complete position with following two conditions.
A. It has open/close limit signal.
B. When the current exceeds this level due to motor stall.
When this parameter is set to 00 “No limit signal”, the methods for detecting open/close
complete position are as follows.
A. When Pr. 0-17 is set to 0: When PG feedback frequency is almost 0 due to motor stall, it is
regarded as open/close complete position.
B. When Pr. 0-17 is NOT set to 0: When current exceeds this level due to motor stall, it is
regarded as open/close complete position.
NOTE
It is recommended to use method B for the transmission mechanism skids easily.
This function is only for the distance control mode. For multi-step control mode, please use the multi-
input terminals (set one of Pr.5-00~Pr.5-10 to 17, 18, 23 or 24).
