⑤ Analog Monitor Signals
There are 3 types of monitoring signals : " Motor Current Monitor (MOTOR_I) " , " Torque Load Monitor
(LOAD) " , and " Rotating Speed Analog Monitor Voltage (SPEED_V) " . Please refer to Fig. 38 for
connections.
16 - 2 External Input / Output Connector B
( 1 ) Details of External Input / Output Connector B ④ Signals
WARNING
・ DO NOT connect any circuit other than SELV ( DC+24V) (Safety Extra Low Voltage) to the
External Input / Output Connector B ④ of the CONTROLLER. This will cause I / O board damage
in the CONTROLLER.
・ Do not supply over voltage or over current into the input / output circuit. Always install a LOAD
(resistor) to the output circuit to eliminate the chance of damage to the CONTROLLER.
CAUTION
Input / Output Connector B ④ DOES NOT use Pin No. 7, No. 8, and No. 15. If pin No. 7, No. 8, and
No. 15 are connected, the CONTROLLER will be damage.
