Actual signals and parameters 161
5 = DI1P, 2P, 3P – Start Forward, Start Reverse, and Stop.
• Start and Direction commands are given simultaneously with two separate
momentary push-buttons (the P stands for “pulse”).
• Start Forward command is through a normally open push-button connected to
digital input DI1. To start the drive, the digital input DI3 must be activated during
the pulse in DI1.
• Start Reverse command is through a normally open push-button connected to
digital input DI2. To start the drive, the digital input DI3 must be activated prior the
pulse in DI2.
• Connect multiple Start push-buttons in parallel.
• Stop is through a normally closed push-button connected to digital input DI3.
• Connect multiple Stop push-buttons in series.
• Requires parameter
1003 = 3 (REQUEST).
8 = KEYPAD – Control Panel.
• Start/Stop and Direction commands are through the control panel when EXT1 is
active.
• Direction control requires parameter 1003 = 3 (REQUEST).
9 = DI1F, 2R – Start/Stop/Direction commands through DI1 and DI2 combinations.
• Start forward = DI1 activated and DI2 de-activated.
• Start reverse = DI1 de-activated and DI2 activated.
• Stop = both DI1 and DI2 activated, or both de-activated.
• Requires parameter
1003 = 3 (REQUEST).
10 = COMM – Assigns the fieldbus Command word as the source for the start/stop
and direction commands.
• Bits 0,1, 2 of Command word 1 (parameter 0301 FB CMD WORD 1 ) activates the
start/stop and direction commands.
• See Fieldbus user’s manual for detailed instructions.
11 = TIMER 1 – Assigns Start/Stop control to Timer 1 (Timer activated = START;
Timer de-activated = STOP). See Group 36: Timed functions .
12…14 = TIMER 2… 4 – Assigns Start/Stop control to Timer 2…4.
See Timer Function 1 above.
20 = DI5 – Start and stop through digital input DI5. 0 = stop, 1 = start. Direction is fixed
according to parameter 1003 DIRECTION (setting REQUEST = FORWARD).
21 = DI5, 4 – Start and stop through digital input DI5. 0 = stop, 1 = start. Direction
through digital input DI4. 0 = forward, 1 = reverse. To control direction, parameter
1003 DIRECTION must be REQUEST.
27 = SUPRV1 OVER – Start when the value of supervision parameter 1 goes over the
supervision high limit. Stop when the value goes below the low limit. See
parameter Group 32: Supervision .
28 = SUPRV1 UNDER – Start when the value of the supervision parameter 1 goes
below the supervision low limit. Stop when the value goes over the high limit. See
parameter Group 32: Supervision .
29 = SUPRV2 OVER – See selection SUPRV1 OVER.
30 = SUPRV2 UNDER – See selection SUPRV1 UNDER.
31 = SUPRV3 OVER – See selection SUPRV1 OVER.
32 = SUPRV3 UNDER – See selection SUPRV1 UNDER.
33 = SDI2 – Start and stop as for SUPRV1 OVER. Direction through
digital input DI2. 0 = forward, 1 = reverse. To control direction, parameter 1003
DIRECTION setting must be REQUEST.
34 = SUP1 UDR+DI2 – Start and stop as for SUPRV1 UNDER. Direction through
digital input DI2. 0 = forward, 1 = reverse. To control direction, parameter 1003
DIRECTION setting must be REQUEST.
