READJUSTMENT
1) For faster response time set larger proportional gain, shorter integral gain and/or
shorter acceleration and deceleration times.
2) To stabilize the system adjust increase anti-hunting gain, increase lag-time constant
and/or slow the response time.
SPECIAL ADJUSTMENTS
1) The touch pad may be used to adjust the setpoint by changing the frequency
reference setting mode selection to touch pad only (2nd function # 9).
2) The touch pad may be used to start and stop the drive by changing the command

sure that jumpers JP1 and JP2 (located on main control printed circuit board PCB1)
are correctly set.
2) SOFTWARE - Make sure that the inverter main software is Version 5.2 (see Section
