J Wiring
WARNING
D Always turn OFF the input power supply before wiring terminals.
Otherwise, an electric shock or fire may occur.
D Wiring should be performed only by qualified personnel.
Failure to observe this warning may result in an electric shock or a fire.
D Make sure to ground the ground terminal .
(200V class: Ground to 100Ω or less, 400V class: Ground to 10Ω or less)
Failure to observe this warning may result in an electric shock or a fire.
D Always check the operation of any emergency stop circuits after they are wired.
Otherwise, there is the possibility of injury. (Wiring is the responsibility of the user.)
D Never touch the output terminals directly with your hands or allow the output lines to
come into contact with the Inverter case. Never short the output circuits.
Otherwise, electrical shock or grounding may occur.
CAUTION
D Verifythat the rated voltage of the Converter coincides with the AC power supply volt-
age.
Failure to observe this caution may result in personal injury or a fire.
D Do not perform a withstand voltage test of the Inverter and the Converter.
It may cause semi-conductor elements to be damaged.
D Make sure to connect the Inverter and the Converter as shown in the connection dia-
grams.
The Inverter or Converter may be damaged.
D Tighten terminal screws to the specified tightening torque.
Failure to observe this caution may result in a fire.
D Never connect the power supply to output terminals U/T1, V/T2, and W/T3.
The Inverter may be damaged.
D Do not connect phase-advancing capacitors or LC/RC noise filters to the output cir-
cuits.
The Inverter may be damaged or internal parts burnt if these devices are connected.
D Do not connect electromagnetic switches or contactors to the output circuits.
If a load is connected while the Inverter is operating, surge current will cause the overcurrent
protection circuit inside the Inverter to operate.

run power cables and signal lines in the same duct or bundle. Noise on signal lines may cause
vibration or malfunctions.
D Never connect a commercial power supply directly to the Motor.
D Use Yaskawa-specified cables. To use other cables, check the rated current of your equipment,
and consider the operating environment to select correct cables. If a cable not specified by Yaskawa is to be used for the Encoder, select a twisted-pair shielded cable.
D The terminal block, connectors, or connector pin layout differ according to the model. Refer to the
manuals for your model before wiring.
D If no terminal block is used, protect lead joints with insulating tubes or tapes.
Failure to observe this caution may result in electrical shock or fire.

Introduction
1.1.1 Features
1.1 Overview
1.1.1 Features
The VS-625M5 Inverter and VS-656MR5 Converter form a highly reliable, high-performance AC drive system
in which an AC spindle motor is controlled by the Inverter using vector control with a regenerative function.
The system ensures stable drive control of machine tools, such as machining centers and lathes, and industrial
machines, such as transfer machines and testing machines, while providing high speed and the ability to handle
tough environmental conditions.
The system has the following features.
J
Multi-axis Driving
The Inverter and Converter are separate units of highly reliable, compact book-type construction. The
Converter incorporates a power regeneration function and multi-axis driving configuration, providing
power to the spindle drive and servo drive with easy control through the control panel.
J Compact
The Inverter and Converter are more compact and ensure higher precision than conventional models. This
was enabled by the development of a compact, high-precision detector, improvement in output voltage
under optimal vector control, and the selection of an optimum cooling construction as a result of thermal
analysis.
J
Compatible with Yaskawa’s YENET1200 Standard Network
The Inverter and Converter are available in models that are compatible with Yaskawa’s YENET1200 standard high-speed serial network, making it possible to reduce the number of wires for CNC connections.
The Inverter and Converter are also available in models that are compatible with analog I/O interfaces as
well so that the Inverter and Converter can be used with the VS-626 Series for conventional spindle driving. Sequence I/O can be connected to 0- and 24-V common terminals.
J
Compact, Lightweight Spindle Motor
The downsizing of the spindle motor was enabled by the optimum electromagnetic design of the system
ensuring ideal heat distribution, improvements in the core and cooling construction of the system, and
changes in the circuit design of the encoder. The system ensures higher reliability under tough environmental conditions than any conventional system.
J
High-precision, High Servo Performance
The system employs a high-speed IGBT (insulated gate bipolar transistor) power element for high−precision, high-frequency PWM control at high speeds, suppressing current distortion that may cause torque
ripples and reducing rotational fluctuations. The system employs a DSP (digital signal processor) as well
to improve the servo performance of the system.
J
Improved Orientation Function
The system performs orientation control to a fixed position using the motor encoder. This function is used
when the motor shaft is connected to the load shaft at a ratio of one to one. For orientation control with
a magnetic sensor, the detected signal of the motor encoder will be used for orientation control to desired
position.
J
Expanded Fixed Output Range via Winding Selection
If a winding selection motor is used, a dedicated electromagnetic contactor will select the winding, making
it possible to expand the fixed output range without an increase in the capacity of the Inverter. This will
eliminate the speed change mechanism of the machinery to enable downsizing.
J
Continuous Regenerative Operation
The Converter and Inverter employ an IGBT so that the Converter will respond to frequent accelerations
and decelerations, suppress temperature rises, and save energy consumption, improving the rate of power
supply regeneration and enabling regenerative control at high speeds.
J
Construction
Inverter and Converter models with external heatsink cooling are available and panel-mounting construction with an integral cooling fan are provided for ease of panel mounting and maintenance.
1-2
J
International Standards
The Inverter and Converter meet EMC and low-voltage directive requirements, allowing machinery
manufacturers to easily acquire CE marking certification.
1.1.2 Inverter Models
Inverter models are offered in both 200 and 400 V classes. Both M5A models for independent drive with
analog speed references and M5N models for NC systems using YENET1200 serial communications are
available in both classes. M5A and M5N models differ from each other in the host control device and in
connection methods.
