Table A.1 F7 Parameter List (Continued)
Description
Sets the Overtorque/Undertorque detection level as a percentage of
Drive rated current or torque for torque detection 1. Current
detection for A1-02 = 0 or 1. Torque detection for A1-02 = 2 or 3.
Sets the length of time an Overtorque/Undertorque condition must
exist before torque detection 1 recognized by the Drive.
Determines the Drive's response to an Overtorque/Undertorque
condition. Overtorque and Undertorque are determined by the
settings in parameters L6-05 and L6-06. The multi-function output
settings "18" and "19" in the H2-
active if programmed.
0: Disabled
1: OL4 at Speed Agree - Alarm (Overtorque Detection only active
during Speed Agree and Operation continues after detection).
2: OL4 at RUN - Alarm (Overtorque Detection is always active and
operation continues after detection).
3: OL4 at Speed Agree - Fault (Overtorque Detection only active
during Speed Agree and Drive output will shut down on an OL4
fault).
4: OL4 at RUN - Fault (Overtorque Detection is always active and
Drive output will shut down on an OL4 fault).
5: UL4 at Speed Agree - Alarm (Undertorque Detection is only
active during Speed Agree and operation continues after
detection).
6: UL4 at RUN - Alarm (Undertorque Detection is always active
and operation continues after detection).
7: UL4 at Speed Agree - Fault (Undertorque Detection only active
during Speed Agree and Drive output will shut down on an OL4
fault).
8: UL4 at RUN - Fault (Undertorque Detection is always active and
Drive output will shut down on an OL4 fault).
Sets the Overtorque/Undertorque detection level as a percentage of
Drive rated current or torque for torque detection 2. Current
detection for A1-02 = 0 or 1. Torque detection for A1-02 = 2 or 3.
Sets the length of time an Overtorque/Undertorque condition must
exist before torque detection 2 is recognized by the Drive.
Torque Limit
Sets the torque limit value as a percentage of the motor rated torque.
Four individual quadrants can be set.
Output torque
Regen. state
Reverse
Regen. state
Negative torque
Hardware Protection
Selects the DB protection only when using 3% duty cycle heatsink
mount Yaskawa braking resistor. This parameter does not enable or
disable the DB function of the Drive.
0: Not Provided
1: Provided
When the cooling fin temperature exceeds the value set in this
parameter, an overheat alarm (OH) will occur.
Selects the Drive operation upon an OH pre-alarm detection.
0: Ramp to Stop
1: Coast to Stop
2: Fast-Stop
3: Alarm Only
Selects the detection of input current phase loss, power supply volt-
age imbalance, or main circuit electrostatic capacitor deterioration.
0: Disabled
1: Enabled
