Regenerative solution

The D1000 kit includes a Regenerative DC bus supply

unit (D1000), EMC filter and low harmonic filter. If the

D1000 kit is purchased, it is not necessary to buy the

EMC filter as separate item.

The R1000 kit includes a Regenerative braking unit

(R1000) and current suppression reactor.

Why won't the Omron Q2A-A4007-AAA Controller motor rotate after entering the run command?
- S
  Steven BeckerAug 10, 2025
  The motor may not rotate after entering the run command for several reasons. The drive might not be in Drive Mode, indicated by the keypad not showing [Rdy]. Ensure the keypad displays [Rdy] or return to the Home screen. A fast stop command could have been received; if so, turn off the fast stop input signal. The settings for the Run command source (b1-02) or the frequency reference source (b1-01) might be incorrect, so verify these settings. Defective wiring in the control circuit terminals or incorrect voltage/current input settings for the master frequency reference could also be the cause. Also, check if the frequency reference is too low, and if so, increase it above the minimum output frequency (E1-09). Finally, confirm the sinking/sourcing mode and power supply settings are correct.

What to do if the Omron Q2A-A4007-AAA motor is too hot?
- J
  Jeffrey MooreAug 16, 2025
  If the Omron Controller motor is overheating, it could be due to a heavy load or continuous operation at very low speed. Reduce the load, increase acceleration and deceleration times, and examine the values set in L1-01, L1-02, and E2-01. Consider using a larger motor. If the motor is running continuously at a very low speed, change the run speed or use a drive-dedicated motor.

Why is the Omron Q2A-A4007-AAA Controller drive frequency reference different from the controller frequency?
- J
  Jessica LopezAug 25, 2025
  The discrepancy between the drive frequency reference and the controller frequency in your Omron system can stem from several factors. The analog input gain and bias for the frequency reference input might be incorrectly configured; examine the settings for Terminals AI1, AI2, and AI3. The drive could be receiving frequency bias signals from analog input terminals AI1 to AI3, with the sum affecting the frequency reference; check parameters H3-02, H3-10, and H3-06. If PID control is enabled and not required, disable it by setting b5-01 = 0.
