Safety
- Drive/power/encoder circuit: hazardous voltages may remain in the DC link after power-off. Lock out / tag out, wait for discharge per the drive documentation, and use qualified personnel only.
Common Causes
- The gradient in the coarse area of the valve characteristic is less than or equal to zero
Troubleshooting Steps
- 1The gradient in the coarse area is calculated as follows: - Positive quadrant: (MD 5485 - MD 5464) / (MD 5486 -5465) - Negative quadrant: (MD 5487 - MD 5467) / (MD 5488 - 5468) Enter a valid combination in the above drive MD.
- 2Clear alarm with the RESET key in all channels. Restart part program. 2-795
