increased. If the FOLLOWING ERROR occurs on an extend move, increase the EXTEND FEED

FORWARD; it the error occurs on a retract move, increase the RETRACT REED FORWARD. If this doesn't

solve the problem, the ACCELERATION and DECELERATION ramps are too steep for the response of the

system. Their values can be reduced, or the ACCEL FEED FORWARD and DECEL FEED FORWARD

terms can be increased. After the problem which caused the error has been corrected, keep moving the axis

back and forth with increasing speed until you reach the desired speed. Should the system seem a little sloppy,

try decreasing the MAXIMUM ERROR and adjusting the PROPORTIONAL GAIN until the axis can be

moved without getting an error. Remember: the parameters are not updated in the MMC120 until the 'P'

command is issued.

Jogging The Axis

You can jog the axis by setting the COMMAND VALUE to the EXTEND LIMIT or RETRACT LIMIT and

using the 'G' and 'H' commands repeatedly. This causes the Motion Control Module to GO and HALT.

Saving Parameters and Profiles

After the system is set up and tuned using DCS120, you need to store the parameter and profile values in the

Programmable Controller. This is done using Command Types A and B. Only the parameters for the axes

used need to be saved, and only the profiles used need to be saved.
