Chapter 2 I/O ports
HA-680_V04 - 34 -
(I/O signal functions for speed control)
CN2-5 Phase-Z (OC): Z (output)
● Function
The port outputs phase-Z pulse signal of the encoder. The signal is outputted one pulse per every one
motor rotation. The signal may be used with the mechanical origin signal as a precise origin of the driven
mechanism.
The transistor is turned on during Phase-Z output.
◆ Connection
(1) An example of [CN2-5 phase-Z: Z] connection is shown in the figure to the right.
(2) The port is insulated by photocouplers.
(response frequency: 10kHz max)
(3) Configure the output circuit for the ports as follows:
Supply voltage: DC24V or less
Signal current: 40mA or less
CN2-6 Output common: OUT-COM (output)
● Function
This is the common port for the [CN2-1, 2, 3, 4, 5] ports.
CN2-7 Servo-ON: S-ON (input)
● Function
This turns the servo power for the HA-680 driver ON and OFF.
After about 100ms from turning the input ON, the servo power of the HA-680 driver is ON and the
actuator can be driven. When OFF, the servo power turns OFF and the motor is free to rotate.
Logic change can be performed with “13: Input pin logic setting” in “Parameter.” With the default value,
servo power turns ON at normal close.
◆ Connection
Connect [NO-contact signal (a-contact)].
Connect +24 V of the input signal external power supply to “CN2-12 Input signal common.”
