HP 30 30 DRV-08 Output Current, DRV-09 Motor Speed, DRV-10 DC Link Voltage, DRV-12 Fault Display

Chapter 6 - Parameter Description [DRV]

Related Functions: I/O-12 to I/O-14 [Reference Inputs] I/O-17 [Filtering Time Constant] I/O-21 to I/O-21 [Step Frequency 4~7]

I/O-01 to I/O-10: Scaling the analog input signals (V1 and I) for frequency reference.

I/O-17: Adjusts the response sensibility of the input terminal to eliminate contact noise.

I/O-21 to I/O-24: Sets the step frequency from 4 to 7.

☞Note: The frequency setting method of ‘Speed 0’ is decided by DRV-04.

DRV-08: Output Current

DRV►	Current		08	0.0
08	0.0 A
Factory Default:		0.0 A		0.0

This code displays the output current of the inverter in RMS.

DRV-09: Motor Speed

DRV► Speed		09	0
09	0rpm
Factory Default:	0rmp		0

This code displays the motor speed in RPM while the motor is running.

Use the following equation to scale the mechanical speed using FU2-74 [Gain for Motor Speed display] if you want to change the motor speed display to rotation speed (r/min) or mechanical speed (m/min).

Motor speed = 120 * (F/P) * FU2-74

Where, F= Output Frequency and P= the Number of Motor Poles

DRV-10: DC Link Voltage

DRV►	DC link vtg		10	----
10	----- V
Factory Default:		---- V		----

This code displays the DC link voltage inside the inverter.

DRV-11: User Display Selection

DRV► User disp		11	0.0
11 Out	0.0 V
Factory Default:	0.0 V		0.0

This code displays the parameter selected in FU2-73 [User Display]. There are types of parameters in FU2-73: Voltage, Watt and Torque.

DRV-12: Fault Display

DRV►	Fault		12	nOn
12	None
Factory Default:		None		nOn

This code displays the current fault (trip) status of the inverter. Use the PROG, ▲ and ▼ key before pressing the RESET key to check the fault content(s), output frequency, output current, and whether the inverter was accelerating, decelerating, or in constant speed at the time of the fault occurred. Press the ENT key to exit. The fault content will be stored in FU2-01 to FU2-05 when the RESET key is pressed. For more detail, please refer to Chapter 7.
