ATC I/O Specifications for Umbrella ATC
The following inputs and outputs are required
Input
Specification RED/GRN refer to color of input bit when viewing in PLC live
debugger
TOOL COUNTER +24VDC PNP shielded 3 wire inductive proximity switch open RED after a tool change
CAROUSEL IN +24VDC Normally Open NO 2 wire magnetic switch closed GRN when carousel is in
CAROUSEL OUT +24VDC Normally Open NO 2 wire magnetic switch closed GRN when carousel is
out
CLAMPED Normally Open NO mechanical switch closed GRN when clamped
UNCLAMPED Normally Open NO mechanical switch closed GRN when unclamped
MANUAL CLAMP Normally Open NO momentary push button close GRN to activate clamp
ORIENT
COMPLETE
Transistor open collector output from inverter 0V orient complete GRN + 24 not
oriented RED
ZERO SPEED/RUN Transistor open collector output from inverter 0V at zero speed GRN +24 when
running RED
AIR LOW Normally Closed NC switch open RED when air pressure is low *
* Low air gauge must be labeled in Bar/kpa and psi Minimum air supply to machine must equal 95psi and
use a 3/8รข airline and cannot be more than 10ft from a larger main supply line
Output Specification
CAROUSEL OUT SOLENOID 120VAC Solenoid momentary activation until input sensor closed
CAROUSEL IN SOLENOID 120VAC Solenoid momentary activation until input sensor closed
UNCLAMP 120VAC Solenoid when activated tool is unclamped
AIR BLOW 120VAC Solenoid always on at the same time as UNCLAMP
ORIENT START Dry relay contact closure interfaced to the inverter
CAROUSEL MOTOR 3 phase AC at control working voltage Motor must have brake
Inverters
Only the Mitsubishi FR A500 series inverter with FR A5AP option card is supported for use in Centroid
