10.10 H: Terminal Functions
558 YASKAWA ELECTRIC SIEP C710617 05F YASKAWA AC Drive GA700 Technical Manual
Setting Function Description Ref.
19 Torque Detection 2
(N.C.)
The terminal deactivates when the drive detects overtorque or undertorque.
OFF : The output current/torque is more than the torque value set with L6-05 [Torque
Detection Level 2], or the level is less than the torque value set with L6-05 for longer
than the time set with L6-06 [Torque Detection Time 2].
903
1A During Reverse
The terminal activates when the motor operates in the reverse direction.
ON : The motor is operating in the reverse direction.
OFF : The motor is operating in the forward direction or the motor stopped.
904
1B During Baseblock
(N.C.)
The terminal deactivates during baseblock. When the drive is in baseblock, the drive
output transistor stops switching and does not make DC bus voltage.
ON : The drive is not in baseblock.
OFF : During baseblock
904
1C Motor 2 Selected
The terminal activates when motor 2 is selected.
ON : Motor 2 Selection
OFF : Motor 1 Selection
904
1D During
Regeneration
The terminal activates on when the motor is regenerating.
ON : Motor is regenerating.
OFF : Motor is operating or stopped.
904
1E Executing Auto-
Restart
The terminal activates when the Auto Restart function is trying to restart after a fault.
904
1F Motor Overload
Alarm (oL1)
The terminal activates when the electronic thermal protection value of the motor overload
protective function is a minimum of 90% of the detection level.
905
20 Drive Overheat
Pre-Alarm (oH)
The terminal activates when the drive heatsink temperature is at the level set with L8-02
[Overheat Alarm Level].
905
21 Safe Torque OFF
The terminal turns on (safety stop state) when the safety circuit and safety diagnosis
circuit are operating correctly and when terminals H1-HC and H2-HC are off (released).
ON : Safety stop state
OFF : Safety circuit fault or RUN/READY
905
22 Mechanical
Weakening
Detection
The terminal activates when the drive detects mechanical weakening.
905
2F Maintenance
Notification
The terminal activates when drive components are at their estimated maintenance period.
Tells the user about the maintenance period for these items:
• IGBT
• Cooling fan
• Capacitor
• Soft charge bypass relay
905
30 During Torque
Limit
The terminal activates when the torque reference is the torque limit set with L7
parameters, H3-02, H3-06, or H3-10 [MFAI Function Select].
906
31 During Speed
Limit
The terminal activates when the speed limit is active.
906
32 In Speed Limit
During Trq Ctrl
The motor accelerates in the forward direction or the reverse direction after enabling
torque control and the externally input torque reference is disproportionate to the load.
The output terminal activates when this speed is not higher than a constant speed and the
motor speed is at the speed limit. This does not include operation when the drive is
stopped.
906
33 Zero Servo
Complete
The terminal activates when positioning in the range set with b9-02 [Zero Servo
Completion Window] completes after sending the Zero-Servo command.
