HOLDING BRAKE
Optional on all models. The holding brake (motor shaft) must never
exceed its maximum speed. Voltage over 22-26 Vdc will lock the axis.
FAN
FKM1 motors do not offer the fan in any of their models.
GENERAL MOUNTING CONDITIONS
Before installing in onto the machine, the anti-rust paint should be
removed from the rotor shaft and the flange. It must always be in a
dry and clean place. Mounted so it is easily inspected, cleaned and
maintained.
Free of corrosive atmosphere and/or explosive gasses or liquids. If
the motor is going to be continously exposed to oil splashes, it should
be protected with a guard.
CAUTION !
When installing pulleys or gears for transmission, avoid
hitting the shaft. Use some tool that is supported in the
threaded hole on the shaft to insert the pulley or the gear.
AXIAL | RADIAL LOADS
A poor alignment between the motor shaft and the machine axis
increases vibration of the shaft and reduces the useful life of bearings
and couplings.
Likewise, exceeding certain maximum radial load values on the
bearings has a similar effect.
Follow these considerations in order to avoid these problems:
 Use flexible couplings for direct coupling.
 Avoid radial and axial loads on the motor shaft making sure not to
exceed the limit values.

IDENTIFICATION
Names
The denomination of each motor is made up of letters and digits that
mean the following. The sales model is stored in the motor encoder.
The drive software can automatically adjust the motor parameters by
reading that ·sales model· from the encoder memory.
