Setting FI Terminal Input Level
0 0 to 10 V input
1 4 to 20 mA input
NOTE: To set constant n043 to 0, cut jumper J1 on the Inverter control PC board.
§ Frequency Reference Retention (n044)
Effective when UP/DOWN or Sample/Hold commands are selected for multi-function contact inputs. To retain the
held frequency reference at power OFF, set constant n044 to 0.
Setting Description
0 Hold reference retained in frequency reference 1 (constant n025)
1 Not retained
§ Operation Method for Frequency Reference Loss Detection (no45)
Select operation in case the frequency reference from control circuit terminal decreases rapidly.
Setting Description
0 No detection
1 Continue to run at 80% of Fmax.
(Operation when 1 is selected)
If frequency reference decreases by 90% within 400ms, operation is performed at 80% of the reference reached
before decreasing.
