Toshiba VF-A7 Setting parameters Setting monitor mode, Speed control mode, Torque control mode

4. Basic operation of the VF-A7	[Speed control mode]
	[Torque control mode]

The VF-A7 inverter has the following three display modes:

[Normal monitor mode]：Normal display mode. The inverter automatically enters this display mode when it is turned on.

This mode enables you to monitor the output frequency and set frequency command values. This mode is also used to display operation status alarm codes and error messages if the inverter trips.

･Frequency command setting => Refer to 3.2.1.

･Status alarms

If something unusual occurs in the inverter, an alarm code and the output frequency are displayed alternately on the LED display.

: Indicates that a current exceeding the over-current stall limit is passed.

: Indicates that an voltage exceeding the over-voltage stall limit is applied.

: Indicates that the load exceeds 50% or more of the overload trip limit.

: Indicates that the temperature in the inverter reaches the overheat protection alarm level (about 85℃)

[Setting monitor mode] :In this mode, you can set inverter's operation parameters. How to set parameters => Refer to 4.1.

[Status monitor mode] ：In this mode, you can monitor inverter's various statuses, for example, the set frequency, the output voltage, the output current and terminal information.

How to use the monitor => Refer to 8.1.

4.1 Setting parameters [Setting monitor mode]

The VF-A7 inverter is shipped with certain parameters factory-set by default. The para meters are broadly classified under the following three groups. First, you need to select the parameter you want to change or check.

[Basic parameter] : Parameters that you need to set before the first use after purchase.

[Extended parameters] : Parameters used for detailed or particular settings

[User parameter] : Used to search for parameters the settings which have been changed and are different from the factory default settlings. Use this parameter to check parameter settings again after confirmation or when changing parameter settings.(Parameter code: )

(For searching for parameters the settings of which have been changed).
