KEYENCE KV-8000 PLC and MC-200 Connection Guide
KEYENCE KV-8000 PLC and MTL MC-200 Connection Guide
This page explains the basic configuration for connecting a KEYENCE KV-8000 Series PLC to an MTL MC-200-7220A servo driver.
The standard configuration uses a positioning unit to send pulse train commands from the PLC to the MC-200 driver. Additional units may be required when the PLC must receive encoder signals, absolute position data, or motor operating information.

Connection Overview
The KEYENCE KV-8000 Series can control the MC-200-7220A using pulse train position commands.
The PLC positioning unit sends command pulses to the driver. The MC-200 then controls the connected μDD Motor according to the configured command format, electronic gearing, acceleration, speed, and position settings.
The required KEYENCE units depend on the signals that must be exchanged between the PLC and the MC-200 driver.
- Pulse train position commands require a positioning unit.
- Incremental encoder feedback requires a compatible high-speed counter input.
- Absolute position data requires a compatible RS-422 serial communication interface.
- Motor current, speed, or position-error monitoring may require an analog input unit.

Compatible MTL Servo Driver
MC-200-7220A
The MC-200-7220A is the digital and analog I/O version of the MC-200 Series servo driver. It can receive pulse train commands from a PLC positioning unit.
Supported pulse command formats include:
- Pulse and direction
- CW and CCW pulse commands
- Two-phase quadrature pulse commands
Important: The pulse output frequency configured in the KEYENCE PLC must remain within the maximum pulse input frequency specified for the MC-200 driver.

Required KEYENCE KV-8000 Units
High-Speed Positioning Unit
Model: KV-SH04PL
The KV-SH04PL sends pulse train position commands from the KV-8000 PLC to the MC-200-7220A.
This unit is required when the MC-200 is controlled using external pulse commands.
The pulse output circuit, signal common, command format, and maximum frequency must be configured to match the MC-200 input specifications.
High-Speed Counter Unit
Model: KV-SSC02
The KV-SSC02 may be used when the PLC must receive incremental A-phase, B-phase, and Z-phase encoder signals from the MC-200 system.
This unit is not required when the PLC only sends commands and does not need an independent encoder count.
Before wiring, confirm the encoder output circuit, signal voltage, maximum response frequency, counting mode, and line receiver requirements.
Serial Communication Unit
Model: KV-XL402
The KV-XL402 is an RS-422A and RS-485 serial communication unit. It may be used when the PLC must receive absolute position data output from the MC-200 driver.
Before implementation, confirm the MC-200 communication format, baud rate, data length, ASCII or binary format, wiring, termination resistance, and PLC receive program.
This unit is not required when the PLC does not need absolute position information.
Analog Input Unit
A compatible analog input unit may be added when the PLC must receive the MC-200 analog monitor output.
Depending on the driver settings, the analog monitor can be used to observe information such as motor current, speed, or position error.
Confirm the selected monitor function, output voltage range, scaling, signal common, and analog input specifications before connection.
