1.2 System requirements
To ensure the most effective and extended use of all equipment, adhere to the following
specifications:
w 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 subjected to excessive shock or stress.
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.
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.
w 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.
w Cable Wiring
P Use the specified cables for all system connections.
P Circuit breakers or fuses are required.
P Avoid using a high-voltage circuit as a frame ground (FG). Also, the frame ground
should be separate from the power ground.
P When multiple Axis Controllers 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 not exceed 50 feet in length and must be run separate from
any high voltage power sources or cabling.
w Installation Environment (Main Controller and Axis Controller Units)
P Controllers must be set in a NEMA 12 enclosure.
Do not use at the following locations: (If these conditions cannot be achieved,
contact FEC INC.)
P Areas under direct sunlight.
P Areas where the environmental temperature is out the 32°F-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 tool or
Controller Unit.
