System requirements
To ensure the most effective and extended use of all equipment, adhere to the following
specifications:
{ 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 adequate bolts. Use the specified bolts to prevent the tool from
loosening due to vibration. The tool assembly contains precision parts and electronic
components, and must not be subject to excessive shocks or stresses.
When designing an application, keep in mind that the torque transducer is a type of
strain gage and, although it has been designed to withstand sudden shock, repeated
shock (over time) could damage the transducer. Therefore, cylinder cushions or shock
absorbers should be used to decelerate the powerhead return 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 rotating time to the machine cycle time) higher than 50%, even when the torque is
below the full scale value.
{ Cable Wiring
P Use the specified cables for all System connections.
P Circuit breakers or fuses are required.
P Do not use a high voltage circuit as a frame ground (FG). Also, the frame ground
should be separate from the power ground.
P When multiple Axis units are used, ensure that each unit is connected to its matching
numbered tool, and that all connectors are locked.
P 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
P Controllers must be set in a NEMA 12 enclosure.
Do not use at the following locations. (If these conditions cannot be avoided, contact
FEC INC.)
P Areas under direct sunlight.
P Areas where the environmental temperature is out the 32 °~122° F range.
P Areas where the relative humidity is out of the 20~90% range.
P Areas where the temperature changes quickly, which may cause moisture.
P Areas where conductive powder, oil mist, saline, or organic solvents exist.
P Areas that have corrosive or combustible gases.
P Areas that have strong electric or magnetic fields.
P Areas where a strong vibration or shock could be transmitted directly to a Controller
unit or tool.
