1. All functions on terminal 18 and 19 are controlled by
an interrupter, which means that the repetitive accu-
racy of the response time is constant. Can be used for
start/stop, setup switch and especially for changing
digital preset, i.e. to obtain a reproducable stop point
when using creep speed. For further information see
VLT 2800 Precise Stop Instruction, MI.28.CX.02.
Function:
In these parameters 302-307 Digital inputs it is possi-
ble to choose between the different enabled functions
related to the digital inputs (terminals 18-33).
Description of choice:
No operation is selected if the frequency converter is
not to react to signals transmitted to the terminal.
Reset resets the frequency converter after an alarm;
however, a few alarms cannot be reset (trip locked)
without first disconnecting the mains supply and re-
connecting it. See table under List of warnings and
alarms. Reset is activated on the leading edge of the
signal.
Coasting stop inverse is used for making the frequency
converter "let go" of the motor immediately (output
