1.5.7 Hand Auto

During normal operation the frequency converter is in Auto mode, where the reference signal is

given externally, analog or digital via the control terminals. However, in Hand mode, it is possible

to give the reference signal locally via the control panel.

On the control terminals, the following control signals will remain active when Hand mode is ac-

tivated:

Hand Start (LCP2) Quick Stop Inverse Thermistor

Off Stop (LCP2) Stop Inverse Precise Stop Inverse

Auto Start (LCP2) Reversing Precise Stop/Start

Reset DC Braking Inverse Jog

Coasting Stop Inverse Setup Select LSB Stop Comm. Via Serial Comm.

Reset and Coasting Stop Inverse Setup Select MSB

Switching between Auto- and Hand mode:

By activating the [Change Data] key in [Display Mode], the display will indicate the mode of the

frequency converter.

Scroll up/down in order to switch to Hand mode, the reference can be changed by using [+]/[-].

NB!

Please note, that parameter 020 may block the choice of mode.

A change of parameter values is saved automatically after a mains failure.

If the display shows three dots at the right, the parameter value has more than three digits. In

order to see the value, activate [CHANGE DATA].
