Data No.19 Torque Inhibit Limit [Nm, Kgm...]
Setting range: 0 ~ [10: Calibration torque] × 1.1
Limit for ignoring the Torque value sensed during fastening start due to inertia. When the initial
Torque exceeds the Torque Inhibit Limit during [61: Torque Inhibit Revolutions] an ABNORMAL
will be generated and fastening will end.
Data No.1A 1P Reverse Torque [Nm, Kgm...]
Setting range: 0 ~ [10: Calibration torque] × 1.1
Maximum torque value that will be applied to the fastener in reverse when using the 1 Pulse
Reverse function.
Used to disengage the socket from the fastener when a locking condition can occur.
Data No.20 Low Angle [deg]
Data No.21 High Angle [deg]
Setting range: 0~9999
Sets the High and Low limits for Fastening Judgment Angle as measured from [16: SNUG
Torque] to Fastening End. If the High limit is reached the fastening operation will stop even if the
operation is not complete. Low limits are reported at the end of the cycle.
Data No.22 Standard Angle [deg]
Setting range: 0~9999
Sets the target Angle value for fastening as measured from [16: SNUG Torque].
Data No.40 Initial Time [sec]
Setting range: 0 ~ 999.9
During initial time, the start of the fastening operation will be conducted at [50: Initial Speed].
When [40: Initial Time] is set as 0, the operation will start at [51: Freerun Speed].
Data No.41 Freerun Time Limit [sec]
Setting range: 0~999.9
Sets the maximum time the system will run at [51: Freerun Speed].
Data No.42 Fastening Time Limit [sec]
Setting range: 0~999.9
Set the high time limit from beginning of the operation to fastening end.
If this time elapses before reaching the target, the process is rejected.
Data No.50 Initial Speed [rpm]
Setting range: Tool’s minimum rpm ~ Tool’s maximum rpm
Sets the speed at which the tool will begin operations. Slower speeds are used to aid in fastener
engagement.
Data No.51 Freerun Speed [rpm]
Setting range: 1 ~ Tool’s maximum rpm
Sets the high speed rundown value used to drive a fastener to seating. Shifts to [52: Slow
Down Speed] when [41: Freerun Time Limit] or [60: Freerun Revolutions] is sensed.
The MNR system will fasten to Standard Torque or Standard Angle (WHICHEVER THE
SYSTEM SENSES FIRST). If fastening to Standard Angle, set Standard Torque equal to
the Calibration Torque of the tool or high enough not to trigger a judgment for
Standard Torque.
To use the 1 Pulse Reverse function [1A: 1P Reverse Torque], [55: 1P Reverse Speed]
and [64: 1P Reverse Time] must all be set up. If any one of these do not have a value
set, the 1 Pulse Reverse function will be disabled.
