Omron 3G3JX Quick Start Guide

14 JX Quick Start Guide
PROGRAMMING JX
• Select Run command source on parameter A002
• Adjust the stopping method by b091 and the acceleration/deceleration ramps on parameters F002 and F003
• Set the motor base frequency and AVR voltage of the motors in parameters A003 and A082
• Set the motor data: rated current (b012), rated power (H003) and number of poles (H004)
At this point the inverter is ready to run the motor for the first time, but first review this check-list:
• Verify the power LED is ON. If not, check the power connections.
• Make sure the motor is disconnected from any mechanical load.
• Make sure that you have a frequency reference checking the content of F001.
• Now give the RUN command from the selected source. The RUN LED will turn ON.
• The motor should start turning.
• Remove the RUN command or press the STOP key to stop the motor rotation.
3.5 Ramps adjustment
The basic frequency (speed) profile is defined by parameters con-
tained in the “F” Group as shown to the right. The set running fre-
quency is in Hz, but acceleration and deceleration are specified in
the time duration of the ramp (from zero to maximum frequency,
or from maximum frequency to zero).
Acceleration 1 and Deceleration 1 are the standard default accel
and decel values for the main profile. Accel and decel values for an
alternative profile are specified by using parameters A092 through
A093.
