56 3-phase stepper motor
4 Installation BRS3
0198441113730, V2.02, 03.2011
4.3 Mechanical installation
Mounting position The following mounting positions are defined and approved as per IEC
60034-7:
• IM B5 drive shaft horizontal
• IM V1 drive shaft vertical, shaft end down
• IM V3 drive shaft vertical, shaft end up
@ WARNING
UNEXPECTED MOVEMENT CAUSED BY ELECTROSTATIC DIS-
CHARGE
In rare cases, electrostatic discharge to the shaft may cause incorrect
operation of the encoder system and result in unexpected motor
movements and damage to the bearing.
• Use conductive components (such as antistatic belts) or other
suitable measures to avoid static charge by motion.
Failure to follow these instructions can result in death, serious
injury or equipment damage.
@ WARNING
UNEXPECTED MOVEMENT
If the approved ambient conditions are exceeded, external sub-
stances from the environment may penetrate and cause unexpected
movement or equipment damage.
• Verify that the ambient conditions are met.
• Do not allow seals to run dry.
• Keep liquids from getting to the shaft bushing (for example in
mounting position IM V3).
• Do not expose the shaft sealing rings and cable entries to the
direct spray of a pressure washer.
Failure to follow these instructions can result in death, serious
injury or equipment damage.
@ WARNING
UNINTENDED BEHAVIOR CAUSED BY MECHANICAL DAMAGE TO
THE MOTOR
If the maximum permissible forces at the shaft are exceeded, this will
result in premature wear of the bearing, shaft breakage or damage to
the encoder.
• Do not exceed the maximum permissible axial and radial forces.
• Protect the shaft from impact.
• Do not exceed the maximum permissible axial force when press-
ing on components.
Failure to follow these instructions can result in death, serious
injury or equipment damage.
