Nominal Cal
This is a calculated value based on the torque output of the motor, the gear ratios and
efficiencies. This is a reference value only and cannot be modified.
Primary
Transducer
Choose which transducer will be used as the primary transducer for control and data
collection. This parameter is only available when a tool with a redundant transducer is
attached.
Torque Cal
This is the specific torque calibration value for the tool. Enter a new value after performing
a lab certification. The Torque Cal should not deviate from the Nominal Cal value by more
than 20%.
Redundant
Transducer
ENABLE or DISABLE the redundant transducer to check the primary transducer’s operation.
This parameter is only available when a tool with a redundant transducer is attached.
When enabled the controller compares the redundant transducer’s signal to the primary
transducer’s signal continuously, even at rest. If the difference in the values exceeds the
Tolerance the controller stops the tool with a shutoff code of T1 ≠T2.
To calibrate a tool with a redundant transducer, first disable the redundant transducer and
select T1 as the Primary Transducer. Calibrate the tool normally. Then select T2 as the
Primary Transducer and calibrate the tool normally. Enable the redundant transducer if
required. Choose the correct Primary Transducer.
Tolerance
This is the specific tolerance value for the redundant transducer to
check against the primary transducer. Units are percentage of Max
Torque of the tool. This parameter is only available when a tool with a
redundant transducer is attached.
