2.3.4 Internal Current Control in VVC

plus

Mode

The frequency converter features an integral current limit
control which is activated when the motor current, and
thus the torque, is higher than the torque limits set in

4-16 Torque Limit Motor Mode

,

4-17 Torque Limit Generator

Mode

and

4-18 Current Limit

.

When the frequency converter is at the current limit during
motor operation or regenerative operation, the frequency
converter will try to get below the preset torque limits as
quickly as possible without losing control of the motor.

2.3.5 Local (Hand On) and Remote (Auto

On) Control

Operate the frequency converter manually via the local
control panel (LCP) or remotely via analog/digital inputs or
serial bus.
Start and stop the frequency converter pressing the [Hand
On] and [Off/Reset] keys on the LCP. Setup required:

0-40 [Hand on] Key on LCP

,

0-44 [Off/Reset] Key on LCP

, and

0-42 [Auto on] Key on LCP

.

Reset alarms via the [Off/Reset] key or via a digital input,
when the terminal is programmed to "Reset".

Local Reference forces the configuration mode to open
loop, independent of the setting of

1-00 Configuration

Mode

.

Local Reference is restored at power-down.
