3.3 Parameter Checking and Setting

OPERATION/CONTROL

The inverter is designed to perform simple variable-speed operation with the factory settings of the parameters. Set the necessary parameters according to the load and operation specifications. Use the operation panel (FR-DU04) to set, charge and confirm the parameter values. For full information on the parameters, refer to “CHAPTER 4 PARAMETERS”(Page 60).

3.3.1 Parameter checking

Pr. 160 "user group read selection" is factory-set to display only the simple mode parameters among the parameters. Set the following parameters as required.

(1) Pr. 160 "user group read selection"

Number
160	9999	0, 1, 10, 11, 9999

•Setting details

For the setting method and in-depth explanation, refer to page 137.

Pr. 160 Setting Description

0All parameters are made accessible for reading and writing.

1Only the parameters registered in user group 1 are made accessible for reading and writing.

10Only the parameters registered in user group 2 are made accessible for reading and writing.

11Only the parameters registered in user groups 1 and 2 are made accessible for reading and writing.

9999 Only the simple mode parameters are made accessible for reading and writing. (Factory setting)

(2) Simple mode parameter list

The following parameters are basic parameters made accessible for reading and writing by setting "9999" in Pr. 160. For details of their functions, refer to Chapter 4 "PARAMETERS" (page 60).

Parameter	Name	Application
Number
0	Torque boost	Used to compensate for a voltage drop in the low frequency range to improve
		motor torque reduction in the low speed range.
1	Maximum frequency	Used to set the upper and lower limits of the output frequency.
2	Minimum frequency
3	Base frequency	Used to match the inverter outputs (voltage, frequency) to the motor rating.
4	Three-speed setting (high speed)	Set these parameters when using the terminals to change the running speeds
5	Three-speed setting (middle speed)
		preset in the parameters.
6	Three-speed setting (low speed)
7	Acceleration time	Used to set the acceleration and deceleration times.
8	Deceleration time
9	Electronic thermal O/L relay	Used to set the current value of the electronic overcurrent protection to protect the
		motor from overheat.
10	DC injection brake operation
	frequency
11	DC injection brake operation time	Used to adjust the stopping accuracy according to the load.
12	DC injection brake voltage
13	Starting frequency
14	Load pattern selection	Used to select the optimum output characteristic that matches the application and
		load characteristics.
19	Base frequency voltage	Used to set the base voltage (e.g. motor's rated voltage).
52	DU/PU main display data selection
53	PU level display data selection	Used to choose the monitoring and output signals.
54	FM terminal function selection
55	Frequency monitoring reference	Used to set the frequency and current values, which are referenced, for the level
56	Current monitoring reference	meter.
57	Restart coasting time	Used to perform automatic restart operation after instantaneous power failure or
58	Restart cushion time	commercial power supply-inverter switchover.
