System requirements
To ensure the most effective and extended use of all equipment, adhere to the following specifica-
tions:
• Tool Installation
Tools generate a great amount of torque during operation, and the reaction force is applied to
the mounting area of the tool. Therefore, tools must be installed in the proper positions and with ade-
quate bolts. Use the supplied bolts to prevent the tool from loosening due to vibration. A minimum of
2mm of clearance is required between tools, with nothing touching a mounted tool that will impact
free movement for torque reaction (or improper torque readings will result). The tool assembly con-
tains precision parts and electronic components, and must not be subject to excessive shocks or
stresses.
Keep in mind that the torque transducer is a strain gage based instrument and, although it
has been designed to withstand sudden shock, repeated shock (over time) could damage the trans-
ducer. Therefore, cylinder cushions or shock absorbers should be used to decelerate spindle slides
and prevent excessive (hard stop) vibration, particularly in short cycle time applications operating at
high speeds.
• Fastening Operation
Avoid fastening beyond the full scale torque. Do not use a duty cycle (the ratio of the tool ro-
tating time to the machine cycle time) higher than
60
%, even when the torque is below the full scale
value.
• Cable Wiring
Use the specified cables for all System connections.
Circuit breakers or fuses are required on branch circuit power feeds to the controllers.
Do not use a high voltage circuit as a frame ground (FG). Also, the frame ground should be
separate from the power ground.
When multiple Axis units are used, ensure that each unit is connected to its matching num-
bered tool, and that all connectors are locked.
PLC I/O cables must be run separate from any high voltage power sources or cabling, and
must not exceed 50 feet in length.
• Control Equipment (Axis units) Installation Environment
Controllers should be located in a NEMA 12 enclosure.
Controller units must be located a minimum of 600 mm from high transient voltage sources
such as transformers, motor starters, AC inverters and AC contactors. If it cannot be avoided,
the units must be properly shielded.
Do not use at the following locations.
Areas under direct sunlight.
Areas where the environmental temperature is out of the 32 °~122° F range.
Areas where the relative humidity is above the 90% range.
Areas where the temperature changes quickly, which may cause moisture.
Areas where conductive powder, oil mist, saline, or organic solvents exist.
Areas that have corrosive or combustible gases.
Areas that have strong electric or magnetic fields.
Areas where a strong vibration or shock could be transmitted directly to a Controller unit or
tool.
