Heat Dissipation
The metal surfaces of the product may exceed 70°C (158°F) during operation.
CAUTION
HOT SURFACES
• Avoid unprotected contact with hot surfaces.
• Do not allow flammable or heat-sensitive parts in the immediate vicinity of hot surfaces.
• Verify that the heat dissipation is sufficient by performing a test run under maximum load
conditions.
Failure to follow these instructions can result in injury or equipment damage.
If there is an incorrect arrangement of multiple motors or an improper setup, the motor may
become very hot. The surface temperature of the motor must not exceed 100 °C on the surface
of the motor laminations during continuous operation.
• Verify that the maximum temperature is not exceeded.
• Verify that there is sufficient heat dissipation by means of good ventilation or heat
dissipation via the motor flange and mounting surface.
Mounting
The motor is designed to be mounted using four screws. The motor flange must be mounted
on a flat surface to avoid mechanical tension from being transmitted to the housing. Painted
surfaces have an insulating effect. During mounting verify that the motor flange is mounted in
such a way as to allow for good electrical and thermal conductivity.
Mounting screw size: #6 (M3.5) Length dependent on mounting plate thickness. Screw threads
into motor housing cannot exceed 0.140” (3.56 mm).
Tightening torque: Tightening torque not to exceed 7.8 lb-in (9 kg-cm).
Mounting Clearance
Leave sufficient clearance around the motor body for air flow as stepper motors can become
very hot. A minimum clearance of 0.5” (12.5 mm) around the sides of the motor body is
required for adequate heat dissipation.
All LMD connections are located on the rear face of the device. Refer to the cable manufacturer
specifications to determine adequate bend radii.
Ambient Conditions
Observe the permissible ambient conditions as listed in “Environmental Conditions” on page
