WARNING
LOSS OF CONTROL
• The designer of any control scheme must consider the potential failure modes of control paths and,
for certain critical control functions, provide a means to achieve a safe state during, and after a path
failure. Examples of critical control functions are emergency stop and overtravel stop.
• Separate or redundant control paths must be provided for critical control functions.
• System control paths may include communication links. Consideration must be given to the
implications of anticipated transmission delays or failures of the link.
• Each implementation of the product must be individually and thoroughly tested for proper
operation before being placed into service.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
For USA: Additional information, refer to NEMA ICS 1.1 (latest edition), “Safety Guidelines for the
Application, Installation, and Maintenance of Solid State Control” and to NEMA ICS 7.1, (latest
edition), “Safety Standards for Construction and Guide for Selection, Installation, and Operation
of Adjustable-Speed Drive Systems”
Drives may perform unintended movements due to mechanical damage to connectors.
Mechanical damage to the connectors may cause erratic or uncontrolled operation. Installation
with a bent or broken mounting flange, motor shaft, or misaligned coupling may cause
unintended behavior and possible destruction of system components as a result.
WARNING
LOSS OF CONTROL, ERRATIC OPERATION AND DESTRUCTION OF MECHANICS
• Do not drop product.
• Leave product in protective packaging until ready for use.
• Carefully inspect connectors prior to installation in a system for mechanical damage.
• Carefully inspect motor shaft and ensure shaft rotates freely without binding.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
Opening LMD heat sinks can affect factory-set encoder alignment and impact Hybrid Motion
Technology (hMT) performance. Tamper seals are used to ensure factory hardware settings
remain unaltered and match the encoder alignment set during the manufacturing process.
WARNING
UNINTENDED EQUIPMENT OPERATION
• Do not open the LMD device housing for any reason.
• Contact a Novanta IMS applications representative if the product exhibits unexplained, erratic, or
incorrect operation.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
Radial (side) loading or axial (thrust) impacts on the shaft may result in premature bearing
failure.
NOTICE
EXCESSIVE RADIAL OR AXIAL LOADS
• Do not exceed the maximum radial or side load limits on the motor shaft.
• Do not apply force that will pull the shaft from the motor as that may compress the pre-load washer,
causing the rotor to move.
• Do not allow the shaft to be subject to impact forces or otherwise struck by external objects.
Failure to follow these instructions can result in equipment damage.
NOTE:
For additional information, contact a Novanta IMS Applications representative.
