WARNING
CAUT ION
NOTE
1.1 Warnings, Cautions and Notes
A Warning contains information which is essential for avoiding a safety hazard.
A Caution contains information which is necessary for avoiding a risk of damage to the
product or other equipment.
A Note contains information, which helps to ensure correct operation of the product.
1.2 Electrical safety - general warning
The voltages used in the drive can cause severe electrical shock and/or burns, and could be lethal.
Extreme care is necessary at all times when working with or adjacent to the drive. Specific warnings
are given at the relevant places in this guide.
1.3 System design and safety of personnel
The drive is intended as a component for professional incorporation into complete equipment or a
system. If installed incorrectly, the drive may present a safety hazard.
The drive uses high voltages and currents, carries a high level of stored electrical energy, and is used
to control equipment which can cause injury.
Close attention is required to the electrical installation and the system design to avoid hazards either
in normal operation or in the event of equipment malfunction. System design, installation,
commissioning/start-up and maintenance must be carried out by personnel who have the necessary
training and experience. They must read this safety information and this User Guide carefully.
The STOP and SAFE TORQUE OFF functions of the drive do not isolate dangerous voltages from
the output of the drive or from any external option unit. The supply must be disconnected by an
approved electrical isolation device before gaining access to the electrical connections.
With the sole exception of the SAFE TORQUE OFF function, none of the drive functions must
be used to ensure safety of personnel, i.e. they must not be used for safety-related functions.
Careful consideration must be given to the functions of the drive which might result in a hazard,
either through their intended behavior or through incorrect operation due to a fault. In any application
where a malfunction of the drive or its control system could lead to or allow damage, loss or injury, a
risk analysis must be carried out, and where necessary, further measures taken to reduce the risk for example, an over-speed protection device in case of failure of the speed control, or a fail-safe
mechanical brake in case of loss of motor braking.
The SAFE TORQUE OFF function may be used in a safety-related application. The system designer
is responsible for ensuring that the complete system is safe and designed correctly according to the
relevant safety standards.

1.4 Environmental limits
Instructions in this guide regarding transport, storage, installation and use of the drive must be
complied with, including the specified environmental limits. Drives must not be subjected to
excessive physical force.
Unidrive M700/M701 / Unidrive HS70/HS71 Control Getting Started Guide 3
Issue Number: 2
1.5 Access
Drive access must be restricted to authorized personnel only. Safety regulations which apply at the
place of use must be complied with.
1.6 Fire protection
The drive enclosure is not classified as a fire enclosure. A separate fire enclosure must be provided.
For further information, refer to the Drive User Guide.
1.7 Compliance with regulations
The installer is responsible for complying with all relevant regulations, such as national wiring
regulations, accident prevention regulations and electromagnetic compatibility (EMC) regulations.
Particular attention must be given to the cross-sectional areas of conductors, the selection of fuses
or other protection, and protective ground (earth) connections.
This guide contains instruction for achieving compliance with specific EMC standards.
Within the European Union, all machinery in which this product is used must comply with the
following directives:
2006/42/EC: Safety of machinery.
2004/108/EC: Electromagnetic Compatibility.
1.8 Motor
Ensure the motor is installed in accordance with the manufacturer’s recommendations. Ensure the
motor shaft is not exposed.
Standard squirrel cage induction motors are designed for single speed operation. If it is intended to
use the capability of the drive to run a motor at speeds above its designed maximum, it is strongly
recommended that the manufacturer is consulted first.
Low speeds may cause the motor to overheat because the cooling fan becomes less effective. The
motor should be installed with a protection thermistor. If necessary, an electric forced vent fan should
be used.
The values of the motor parameters set in the drive affect the protection of the motor. The default
values in the drive should not be relied upon.
It is essential that the correct value is entered in Pr 00.046 motor rated current. This affects the
thermal protection of the motor.
1.9 Mechanical brake control
The brake control functions are provided to allow well co-ordinated operation of an external brake
with the drive. While both hardware and software are designed to high standards of quality and
robustness, they are not intended for use as safety functions, i.e. where a fault or failure would result
in a risk of injury. In any application where the incorrect operation of the brake release mechanism
could result in injury, independent protection devices of proven integrity must also be incorporated.
1.10 Adjusting parameters
Some parameters have a profound effect on the operation of the drive. They must not be altered
without careful consideration of the impact on the controlled system. Measures must be taken to
prevent unwanted changes due to error or tampering.

2Introduction
This guide covers the Unidrive M700/HS70 and Unidrive M701/HS71 products.
Unidrive M700/HS70 / Unidrive M701/HS71 features
• Analog and digital I/O with single channel SAFE TORQUE OFF input
• NV Media Card for parameter copying and data storage
• Universal high performance drive for induction, servo, permanent magnet and linear motors
• Flexibility with speed and position measurement, supporting multiple devices and all common
interfaces
• Ethernet fieldbus communication (Unidrive M700/HS70)
• Provides an equivalent for Unidrive SP (Unidrive M701/HS71)
• 485 serial communication interface (Unidrive M701/HS71)
2.1 Operating modes
The drive is designed to operate in any of the following modes:
1. Open loop mode
Open loop vector mode
Fixed V/F mode (V/Hz)
Quadratic V/F mode (V/Hz)
2. RFC - A
With position feedback sensor
Without position feedback sensor (Sensorless)
3. RFC - S
With position feedback sensor
Without position feedback sensor (Sensorless)
2.1.1 Open loop mode
The drive applies power to the motor at frequencies varied by the user. The motor speed is a result of
the output frequency of the drive and slip due to the mechanical load. The drive can improve the
speed control of the motor by applying slip compensation. The performance at low speed depends
on whether V/F mode or open loop vector mode is selected.
Open loop vector mode
The voltage applied to the motor is directly proportional to the frequency except at low speed where
the drive uses motor parameters to apply the correct voltage to keep the flux constant under varying
load conditions.
Typically 100 % torque is available down to 1 Hz for a 50 Hz motor.
Fixed V/F mode
The voltage applied to the motor is directly proportional to the frequency except at low speed where a
voltage boost is provided which is set by the user. This mode can be used for multi-motor
applications.
Typically 100 % torque is available down to 4 Hz for a 50 Hz motor.
Quadratic V/F mode
The voltage applied to the motor is directly proportional to the square of the frequency except at low
speed where a voltage boost is provided which is set by the user. This mode can be used for running
fan or pump applications with quadratic load characteristics or for multi-motor applications. This
mode is not suitable for applications requiring a high starting torque.

Issue Number: 2
2.1.2 RFC-A mode
Rotor Flux Control for Asynchronous (induction) motors (RFC-A) encompasses closed loop vector
control with a position feedback device
With position feedback
For use with induction motors with a feedback device installed. The drive directly controls the speed
of the motor using the feedback device to ensure the rotor speed exactly as demanded. Motor flux is
accurately controlled at all times to provide full torque all the way down to zero speed.
Without position feedback (Sensorless)
Sensorless mode provides closed loop control without the need for position feedback by using
current, voltages and key motor parameters to estimate the motor speed. It can eliminate instability
traditionally associated with open loop control such as operating large motors with light loads at low
frequencies.
2.1.3 RFC- S
Rotor Flux Control for Synchronous (permanent magnet brushless) motors (RFC-S) provides closed
loop control with position feedback device.
With position feedback
For use with permanent magnet brushless motors with a feedback device installed.
The drive directly controls the speed of the motor using the feedback device to ensure the rotor
speed is exactly as demanded. Flux control is not required because the motor is self excited by the
permanent magnets which form part of the rotor.
Absolute position information is required from the feedback device to ensure the output voltage is
accurately matched to the back EMF of the motor. Full torque is available all the way down to zero
speed.
Without position feedback
For use with permanent magnet brushless motors without a feedback device installed.
Flux control is not required because the motor is self excited by the permanent magnets which form
part of the rotor.
Full torque is available all the way down to zero speed, with salient motors.

3.3 Shield connections
The following guidelines should be followed to ensure suppression of radio-frequency
emission and good noise immunity. It is particularly recommended that the guidelines for the
encoder cable be followed closely in order to avoid disturbance to the encoder operation from
electrical noise. Use the grounding bracket and grounding clamp supplied with the drive to terminate
the shields at the drive.
Figure 3-4 Grounding of signal cable shields using the grounding bracket
Control connections Introduction
Control connections
Getting started
Motor cable: Use a motor cable with an overall shield. Connect the shield of the motor cable to the
ground terminal of the motor frame using a link that is as short as possible and not exceeding 50 mm
(2 in) long. A full 360 ° termination of the shield to the terminal housing of the motor is beneficial.
Encoder cable: For best shielding use cable with an overall shield and individual shields on twisted
pairs, connect the cable as illustrated in Figure 3-5. Clamp the overall shield to grounded metallic
surfaces at both the encoder and the drive.
Brake resistor cable: The optional braking resistor should also be wired with shielded cable. If
unshielded wire is required refer to the Drive User Guide for guidance.
Control cables: If the control wiring is to leave the enclosure, it must be shielded and the shield(s)
clamped to the drive using the grounding bracket. Remove the outer insulating cover of the cable to
ensure the shield(s) make contact with the bracket, but keep the shield(s) intact until as close as
possible to the terminals.
