12 Linear
Setting Range:
Linear, S-Curve, U-Curve
Factory Default: Linear
[FUN 11] and [FUN 12] selects different
combinations of acceleration and deceleration
patterns.
Linear:
This is the general acceleration and
deceleration pattern for constant torque applications.
[Acc./Dec. Pattern: ‘Linear’]
S-Curve:
This pattern allows the motor to
accelerate and decelerat smoothly. At this time, the
actual acceleration and deceleration time are longer
about 10% than the acceleration and deceleration
time set in DRV 01-02.
[Acc./Dec. Pattern: ‘S-Curve’]
U-Curve:
This pattern provides more efficient
control of acceleration and deceleration in the
application like winding machines.
[Acc./Dec. Pattern: ‘U-Curve’]
FUN 13: Output Voltage Adjustment
FUN
¢º
Volt control
13 100 %
Setting Range: 40 to 110%
Factory Default: 100%
This function is used to adjust the output voltage of
the inverter. This is useful when using a motor with a
lower rated voltage than the main input voltage.
When this is set at 100%, the inverter outputs its
rated voltage.
