In V/Hz regulation, this parameter configures the V/Hz ratio. Base frequency is the
frequency at which the output voltage reaches MOTOR NAMEPL VOLTS (H.000).
Below base frequency, the output voltage varies with output frequency according to
the V/Hz adjustment in VHZ-CURVE TYPE (H.018). Above base frequency, output
voltage is held constant as frequency increases (constant horsepower range).
The V/Hz ratio is affected by the selection of VHZ-CURVE TYPE (H.018) and the
setting of TORQUE BOOST VOLTAGE (H.003).
*The actual range of this parameter is based on the values of MOTOR POLES (U.002)
and MOTOR NAMEPL BASE FRQ (U.003). See the software I/M for calculations.
If the value of this parameter is too close to the synchronous RPM, the drive might be
unstable. This value directly affects torque linearity and the maximum attainable
horsepower.
MOTOR NAMEPL BASE FRQ (H.001 or U.003)
In vector regulation,
this parameter
identifies the motor
base frequency as it
appears on the motor
nameplate.
Parameter Range:
15.0 to 240.0 HERTZ (vector)
30.0 to 200.0 HERTZ (V/Hz)
Default Setting:
60.0 HERTZ
Parameter Type:
Configurable
!
ATTENTION: The setting of parameters U.001 (Encoder PPR), U.002
(Motor Poles), U.003 (Motor Nameplate Base Frequency), and U.005
(Motor Nameplate RPM) determins the motor manximum speed. These
parameters must be set by a qualitifed person who understands the
significance of setting them accurately. Failure to observe this
precaution could result in bodily injury.
MOTOR NAMEPL RPM (U.005)
Indentifies the motor
rated RPM as it
appears on the motor
nameplate.
.
Parameter Range:
675 to 3596*
Default Setting:
Power Module-dependent. See the software I/M for
more information.
Parameter Type:
Configurable
MOTOR NAMEPL HP (U.022)
Identifies the motor
horsepower as it
appears on the motor
nameplate.
Parameter Range:
0.3 to 600.0 HP
Default Setting:
Power Module-dependent. See the software I/M for
more information
Parameter Type:
Configurable
