Product Notice
Use of OMNIDRIVEs
OMNIDRIVEs are intended for use as transistorized electronic amplifiers powering servo motors in machinery. As
such, they must be part of a controlled system that includes a controlling device. They are not intended to indepen-
dently control a motor. Instructions in the motor and control system manuals must be observed; this document does
not replace those instructions.
Unless specified otherwise, OMNIDRIVEs are intended for use in a normal industrial environment, installed in a
suitable electrical cabinet without exposure to excessive or corrosive moisture or abnormal ambient temperatures.
The exact operating conditions may be established by referring to the data for the drive. The connection and control
of drives in machinery is a skilled operation, disassembly or repair must not be attempted. In the event that a drive
fails to operate correctly, contact the place of purchase for return instructions.
Safety Notes
There are some possible hazards associated with the use of drives. The following precautions should be observed.
Specific Warnings and Cautions are listed in the Preface to the manual.
Installation and Maintenance:
ified service personnel, paying particular attention to possible electrical and mechanical hazards.
Large drives are heavy, the center of gravity may be offset and removable covers shield internal compo-
Weight:
nents. When handling, take appropriate precautions and lift the equipment using permanent, fixed surfaces, such as
the base; avoid lifting the device using protective cover shields that may be loose. Beware of sharp edges; use protec-
tive gloves when handling such assemblies.
Flying Leads and Loose Cables:
ging or entanglement, or are disconnected before carrying drives with such leads or cables.
If a motor is driven mechanically, it may generate hazardous voltages which are conducted from its

power input terminals to the drive. The power connector must be suitably guarded to prevent a possible shock hazard.
When running an unmounted drive, ensure that the cooling fan is adequately guarded and sufficient
Loose Drives:
airflow is provided around the drive to ensure adequate cooling. The mounting surface of the drive is a heatsink and
its surface temperature may increase when the drive is operating. If a motor is connected to the drive, remove the key
which otherwise could fly out and restrain the motor before applying power to the drive.
Damage to cables or connectors may cause an electrical hazard. Ensure there is no damage
Damaged Cables:
before energizing the system.
Drives connect to a permanent main power source; not a portable power source. Suitable fusing and circuit
Supply:
protection devices are required. Consult the instructions and adhere to local and national regulations before connect-
ing and energizing the drive. Current limits must be set correctly when operating a ODM-075 using a single phase
power source.
Logic signals from the drive are interruptible signals; they are removed when power is
Safety Logic Signals:
removed from the drive. Consult the manual for information on auxiliary power connections that may be employed
when these signals are used for safety purposes.
The safe incorporation of OMNIDRIVE products into a machine system is the responsibil-

ity of the machine designer, who should comply with the local safety requirements at the place where the machine is
to be used. In Europe this is likely to be the Machinery Directive, the ElectroMagnetic Compatibility Directive and
the Low Voltage Directive. In the United States this is likely to be the National Electrical Code.

trols and protection. Installation information for the drive is provided in the manual and list the minimum installation
requirements for the drive are provided in the manual. Motors and controlling devices that connect to the drive should
have specifications that complement the capabilities of the drive.
Motors controlled by the drive should only connect to the drive; they should not connect directly to the AC

line. Use of custom motors requires the entering of a valid thermal time constant, otherwise the motor overload pro-
tection will not function properly.
: OMNIDRIVEs do not contain hazardous substances. They may be disposed of as mechanical scrap. You
