from the zero to proximity switch is greater than 100 000 steps, less than 100010 steps). Design
analysis: the variable displacement of this movement does not know its precise value, but only
know it's a general range (belong to a unknown variable). We use a method for interrupting
operation to solve this problem. We connect the limit switch to the A operating port, Due the
interrupt operation,the motor will slow down to stop, If run to the limit switch as a high-speed
directly,will produce overshoot, In order to avoid the overshoot, we use this method that the first
run as a high-speed ,then run as a low-speed (low-speed is below the starting frequency).
Parameter List:(Enter the parameter setting mode to modify) Setting A Operator address nA = 04,
other parameters are ignored.
Program Listing :( enter the program edit state)
00 SPEED 39000 ; assign the speed as 39KHz
01 G-LEN 0099000 ; First, high-speed close to, but can’t hit the limit switch
02 SPEED 00400 ; low-speed frequency must below the starting frequency
03 G-LEN 07999999 ; The amount of displacement is set to the maximum, to reach the limit
switch
04 SPEED 39000 ; A Operator, assign the return to zero speed as 39KHz
05 GO-AB -A ; In the opposite direction, running the same amount of displacement,back to zero
06 END; the program ends!
