Wiring
• Digital Inputs – Continuous
– Single-pole, double throw (SPDT)
– 2-wire Start/Stop using term 18.
– Reverse using term 19 (P 303) – P 200 set to Both Directions
– Other functions: Quick Stop, Direction Change, Ramp 2
Continuous Switch
This diagram shows a 2-wire Start/Stop using terminal 18 which is programmed for Start.
When the switch is ON, the drive starts. When the switch is OFF the drive stops. The
switch wired to terminal 19 determines direction when the drive is ON. With 0Vdc going to
terminal 19, programmed for Reversing, the drive goes forward. When +24Vdc goes into
terminal 19, the drive goes backward, assuming that parameter 200 has been set to “Both
Directions”.
Continuous switches can also be used for a number of other different functions, such as
Quick Stop, Ramp 2, Clockwise only, jog, preset speeds, changing setups and safety
interlock. For more information see the chart right before parameter 300 in the VLT 5000
instruction manual.
