output". The maximum set value of AI1 is motor rated voltage.
Under V/f separated pattern 2, "AI1 + process PID" output is a proportional value whose
maximum set value corresponds to 200%. This proportional value is multiplied by the voltage
calculated according to linear V/f to obtain drive output voltage.
d1-19
Digital set voltage on V/f
separated pattern
Range: 0.0%~100.0%
Factory default:
0.0%
When 0 is selected at d1-18, the output voltage will be determined by d1-19.
d1-20
Voltage variation time on
V/f separated pattern
Range: 0.00s~600.00s
Factory default:
0.01s
Sets the output voltage change rate under V/f separation pattern. This parameter value is the
time rising from 0V to motor rated voltage or dropping from rated voltage to 0V.
Group d2 Vector Control Parameters of Motor 1
Set control parameters in Group d2 when motor 1 is selected as current load motor on which
sensor-less vector control is performed.

Under sensor-less vector control (SVC), motor speed is kept at set value by automatic speed
regulator (ASR). ASR parameters should be set in d2-01~d2-06.
The proportional gain Kp and integration time Ti of ASR can be set through d2-01~d2-04 so as
to change the speed response characteristic under SVC. Increment of proportional gain Kp can
bring in fast response of the system. However, bigger Kp value will bring about larger system
oscillation.
