2nd Motor Starting Frequency Exceeds Lower Limit
Omron · MX2 Inverter
What does 232 mean?
For the second motor settings, this warning indicates that the inverter's starting frequency (b082) is set higher than the 2nd frequency lower limit (A262). This could lead to unexpected motor behavior if the second motor attempts to start below its commanded minimum frequency, potentially causing jerky motion.
Common Causes
- Parameter b082 (Inverter starting frequency) for the second motor is set to a value higher than its 2nd frequency lower limit (A262).
- The drive's configured starting frequency (b082) is outside the valid range defined by its operational lower limit (A262).
- During parameter tuning, A262 was set to an inappropriately low value relative to the desired starting frequency b082.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Read the current values of parameter b082 (Inverter starting frequency) and parameter A262 (2nd frequency lower limit).
- 2
Adjust parameter b082 to be less than or equal to parameter A262, ensuring the starting frequency is within the operational lower limit.
- 3
Alternatively, if a higher operational lower limit is desired, increase A262 to a value greater than or equal to b082.
- 4
Store parameter changes to the drive's memory and power cycle the drive.
