Digital Inputs, 5-1* continued
All = Terminals 18, 19, 27, 29, 32, 33, X30/2, X30/3, X30/4. X30/ are the terminals on MCB 101.
Functions dedicated to only one digital input are stated in the associated parameter.
All digital inputs can be programmed to these functions:
[0] No operation
[1] Reset
[2] Coast inverse
[3] Coast and reset inverse
[5] DC brake inverse
[6] Stop inverse
[7] External Interlock
TR200 Programming Guide
(Terminal 29 and 33 only) Input for increment counting in the SLC coun-
ter.
(Terminal 29 and 33 only) Input for decrement counting in the SLC coun-
ter.
Input for reset of counter B.
Forces the adjustable frequency drive into sleep mode (see par. 22-4*).
Reacts on the rising edge of signal applied!
Resets all data in par.16-96
No reaction to signals transmitted to terminal.
Resets adjustable frequency drive after a TRIP/ALARM. Not all alarms
can be reset.
Leaves motor in free mode. Logic '0' => coasting stop.
(Default Digital input 27): Coasting stop, inverted input (NC).
Reset and coasting stop Inverted input (NC).
Leaves motor in free mode and resets the adjustable frequency drive.
Logic '0' => coasting stop and reset.
Inverted input for DC braking (NC).
Stops motor by energizing it with a DC current for a certain time period.
See par.2-01 DC Brake Current
[RPM]. The function is only active when the value in par.2-02
Time is different from 0. Logic '0' => DC braking.
Stop Inverted function. Generates a stop function when the selected ter-
minal goes from logical level '1' to '0'. The stop is performed according
to the selected ramp time (par.3-42
3-52
Ramp 2 Ramp-down Time, par.3-62
3-72 Ramp 4 Ramp-down Time).
NOTE: When the adjustable frequency drive is at the torque limit and has
received a stop command, it may not stop by itself. To ensure that the
adjustable frequency drive stops, configure a digital output to
& stop
[27] and connect this digital output to a digital input that is con-
figured as coast.
Same function as Coasting stop, inverse, but External Interlock generates
the alarm message 'external fault' on the display when the terminal
which is programmed for Coast Inverse is logic '0'. The alarm message
will also be active via digital outputs and relay outputs, if programmed
for External Interlock. The alarm can be reset using a digital input or the
[RESET] key if the cause for the External Interlock has been removed. A
delay can be programmed in par.22-00
Interlock Time. After applying a signal to the input, the reaction described
