• Zone J: Under normal conditions the emergency stop switch is
CLOSED. Therefore, a current loop forms in the E_STOP circuit. At
this time, the reading of E_STOP is 0 and the RELAY(R_E_STOP) is
activated. When the E_STOP switch is pressed down, the input current
loop cuts off. The signal value of E_STOP becomes 1 and PCI-1241/
1242 will disable pulse output and make the output of DAC become 0
V.
• Zone K: The software can use P_RDY point (position ready) to com-
municate with a peripheral circuit to inform that the software state is
ready. Using P_RDY, the P_RDY value in PCI-1241/1242 software
should be changed from 1 to 0.
• Zone L: NFB (No Fuse Break for 110 or 220 VAC).
• Zone M: Controllable electromagnetic contactor. The control activa-
tion coil is labeled MC.
• Zone N: The ALARM signal of SERVO MOTOR DRIVER.
• Zone O: In zone J, if the E_STOP switch is not pressed down, the
linked switch R_E_STOP is closed. In zone K, if the system outputs a
POSITION READY signal, the linked switch R_P_RDY is closed. In
zone N, if the driver operates normally, the linked switch ALARM is
opened. If the above conditions are all hold and the SERVO ON switch
is closed, the current loop in Zone O holds and relay MR is activated. It
makes the linked switch MR in zone P closed and then the control coil
MC of the magnetic contact M is activated. Finally the magnetic con-
tact M is closed and the power to the driver is linked.
Caution:
The E_STOP function is disabled when JP5
(E_STOP) is shorted. (Default: JP5 short). For
emergency stop function works properly, it is
necessary to remove the jumper on JP5
(E_STOP)
