Function Code for variable torque load.)
Acceleration/Deceleration 0.2 to 3600 seconds (independent acceleration/deceleration)
Characteristics 4 selectable linear and non-linear "S" curve characteristic.
Internal Functions: The quality of the sound produced by the motor can be changed to
Operating Sound Selection reduce irritating noise.
Frequency Meter Adjustment Scale calibration of externally connected analog meter (6.5-10.5 VDC) or pulse frequency
6 to 100 times output frequency.
Data Protection Data lock is possible to ensure that the data codes are not changed.
Pattern Operation Seven independent stages (frequency up to 400 Hz, duration up to 6,000 seconds each.
Configuration:
Single cycle
Repeat cycling
Single cycle with continuous 7th speed
Momentary Power Five selections available. (Refer to Power Supply Specification.)
Loss Ride Thru
High/Low Limiter Output frequency upper and lower range limit 0 to 400 Hz; 1 Hz step settings.
Bias Magnitude of the zero offset can be set from 0 to 100% of maximum
frequency (1 Hz steps.)
Gain Output frequency gain corresponding to the reference signal can be set
from 0 to 200% (0.1% steps.)
Programmable Jump Frequency Three selectable frequencies can be set to avoid a mechanical resonant point. Width is
adjustable from 0 to 30 Hz (1 Hz steps.)
Slip Compensation Control Maintains motor at constant speed with load fluctuations.
Adjustable from -9.9 Hz to +5.0 Hz.
Torque Limit Control Output torque can be controlled within a range of 20% to 180% (1% steps.)
7 Step Preset Speed 7 programmable preset speeds selectable by 3 contact closures.
Momentary or Maintained Selection between the maintained contact operation/stop command (2-wire operation) or
Contact Operation the momentary contact (3-wire operation).
Terminal Function Change Multi-Use terminals changed via Function Code settings.
X1 to X5 inputs; Y1 to Y5 outputs.
Line to Drive Transition Logic Motor transfer function from the AC line to Drive operation.
Sensorless Vector Control – Improves torque characteristics throughout speed range.
– Improves speed regulation.
