V/Hz Curve Type; Results Of V/Hz Identification Procedure - Reliance electric GV3000/SE Instruction Manual

Input Power/Snubber Configuration (continued)
Param. 0= AC-Input unit with bus-regulator and ride-thru enabled
Range: 1= AC Input unit with ride-thru enabled and Dynamic Braking used. (not bus-regulator to
extend slow down time)
2= DC Input unit with bus-regulator and no ride thru selection. (System 1Q. application)
3= DC Input unit without bus-regulator and without ride thru. (System 4Q application).
4= DC Input unit with all function as 0 for single drive application.
5= DC Input unit with ride thru but Dynamic Braking used (no bus-regulator used.) for single
Drive with 4 Q application.
The selections 0 or 1 are to be used on standard units (version without bus regulator)
The selections 2 or 3 are to be used at multi-drive system application.
The selections 4 or 5 are to be used at single-motor DC supplied application.
H.018

V/Hz Curve Type

Parameter Range: 0 = Linear V/Hz curve
1 = Optimized V/Hz curve
2 = Squared V/Hz curve
Initial Setting: 0
Refer to: H.003 Torque Boost Voltage
Type: Configurable (at standby only)
Description: This parameter provides an application-dependent selection of torque availability (motor
voltage) versus frequency. This selection is effective from any control source (P.000).
H.018=0 : The linear V/Hz curve is used for constant torque versus speed requirements (as
extruders, conveyors). With Torque Boost Voltage (H.003) = 0 a motor IR-compensation
is automatically performed to achieve constant torque availability at low frequencies.
For multimotor connection to inverter (H.003) Torque Boost Voltage may be set > Zero to
provide constant torque availability.
H.018=1 : for use with Rockwell Automation RPM AC motors. A special V/Hz curve (with two
different slopes) will provide constant torque capability and best efficiency.
H.018=2 : for centrifugal fan and pump motor applications.
H.019

Results of V/Hz Identification Procedure

Description: This parameter displays the result of the identification procedure. Normally, the
identification procedure will be successful, and the value in H.019 will be = 0.
Parameter 0 = Ident. procedure successful. No fault.
Range: 1 = A logged error aborted identification procedure. Refer to Section 7, Error Log, for how
to determine the fault cause. Remove the cause and repeat the procedure.
2 = A Function Loss aborted the identification procedure. Depending on Function Loss
Type Mode (P.026), this is or is not logged. Eliminate the cause and repeat the
procedure.
3 = A stop command aborted the identification procedure. Repeat procedure without
stopping.
4 = The identification procedure aborted because the measured current feedback signal is
too low. Feedback signal elements or wiring is defective. Check motor connections,
inverter wiring, and feedback devices (current sensors). Repeat procedure.
6 = Calculation result based on identification procedure measurements is out of range.
Check causes of incorrect measurements, such as motor connections. Repeat
procedure.
Initial Setting: 0
Type: Output parameter.
Refer to: Refer to section 7, Troubleshooting, how to access and read H.019.
