Chapter 2 I/O ports
HA-680_V04 - 45 -
(I/O signal functions for torque control)
CN2-3 Ready: READY (output)
Function
The output turns ON when the driver becomes ready to drive after initialization, and the driver is possible
to communicate with a host.
Logic change can be performed with “14: Output pin logic setting” in “Parameter.” With the
factory-shipped value, the transistor is turned on during normal operation.
Note: The output keeps ON even in alarm status.
Connection
(1) The figure to the right shows an example of the [CN2-3
Ready: READY] port connection.
(2) Configure the output circuit for the port as follows:
Supply voltage: DC24V or less
Signal current: 40mA or less (per port)
CN2-4 Current limiting: CUR-LMT-M (output)
Function
This is outputted while the current limit input signal is inputted and the current is limited to the specified
current.
Logic change can be performed with “14: Output pin logic setting” in “Parameter.” With the
factory-shipped value, the transistor is turned on during the current limiting.
Connection
(1) The figure to the right shows an example of the [CN2-4
Current limiting: CUR-LMT-M] port connection.
(2) Configure the output circuit for the port as follows:
Supply voltage: DC24V or less
Signal current: 40mA or less (per port)
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
