Phase A pulse input + B19 A19 PULSE A + •Inputs + (plus) side of phase A pulse.
Phase A pulse input - B18 A18 PULSE A - •Inputs - (minus) side of phase A pulse.
Phase B pulse input + B17 A17 PULSE B + •Inputs + (plus) side of phase B pulse.
Phase B pulse input - B16 A16 PULSE B - •Inputs - (minus) side of phase B pulse.
Pulse input common B15 A15
PULSE
COM
•Common for pulse input
•It is common between channels.
Preset input common B13 A13
PRST
COM
•Common for preset input
•It is separated between channels.
Preset input 24V B12 A12 PRST
•Turn ON to execute the preset by the external signal.
•When the preset input terminal (PRST) is turned ON, the present
value (Un\G12 and 13) is changed to the preset value setting (Un\G4
and 5).
Latch counter input
common
B09 A09
LATCH
COM
•Common for latch counter input
•It is separated between channels.
Latch counter input
24V
B08 A08 LATCH
•Turn ON to latch the present value (Un\G12 and 13) by the external
signal.
•When the latch counter input terminal (LATCH) is turned ON, the
present value (Un\G12 and 13) is latched and stored in the latch
count value (Un\G14 and 15).
Coincidence output
No.1
B05 A05 EQU1
Executes the coincidence output when a coincidence of the count
value is detected while using the coincidence output function or the
continuous comparison function.
Coincidence output
No.2
B04 A04 EQU2
External coincidence
output power supply
12/24V
B03 A03 12V/24V
•Supplies 12V or 24V when executing the external coincidence output.
•It is common between channels.
External coincidence
output power supply
GND(0V)
B02 A02 0V
•Inputs 0V when executing the external coincidence output.
•It is also used as a common for external coincidence output.
•It is common between channels.
