11.10 H: Terminal Functions
534 YASKAWA SIEPC71061705H GA700 Series Technical Manual
Setting Value Function Description Ref.
16 Frequency Detection 4
The terminal activates when the output frequency > L4-03 [Speed Agree Detection Level(+/-)]. After the terminal
activates, the terminal stays activated until the output frequency is at the value of “L4-03 - L4-04”.
Note:
• The detection level set in L4-03 is a signed value. The drive will only detect in one direction.
• The drive outputs the motor speed status when A1-02 = 3, 7 [Control Method Selection = CLV, CLV/PM].
ON : The output frequency > L4-03
OFF : The output frequency < “L4-03 - L4-04”, or the output frequency ≤ L4-03
836
17 Torque Detection 1 (N.
C.)
The terminal deactivates when the drive detects overtorque or undertorque.
OFF : The output current/torque > L6-02 [Torque Detection Level 1], or the output current/torque < L6-02 for
longer than the time set in L6-03 [Torque Detection Time 1].
837
18 Torque Detection 2 (N.
O.)
The terminal activates when the drive detects overtorque or undertorque.
ON : The output current/torque > L6-05 [Torque Detection Level 2], or the output current/torque < L6-05 for
longer than the time set in L6-06 [Torque Detection Time 2].
837
19 Torque Detection 2 (N.
C.)
The terminal deactivates when the drive detects overtorque or undertorque.
OFF : The output current/torque > L6-05 [Torque Detection Level 2], or the output current/torque < L6-05 for
longer than the time set in L6-06 [Torque Detection Time 2].
837
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.
837
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
838
1C Motor 2 Selected
The terminal activates when you select motor 2.
ON : Motor 2 Selected
OFF : Motor 1 Selected
838
1D During Regeneration
The terminal activates on when the motor is regenerating.
ON : Motor is regenerating.
OFF : Motor is operating or stopped.
838
1E Executing Auto-Restart
The terminal activates when the Auto Restart function is trying to restart after a fault.
838
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.
838
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].
839
21 Safe Torque OFF
The terminal activates (safety stop state) when the safety circuit and safety diagnosis circuit are operating correctly
and when terminals H1-HC and H2-HC are OFF (Open).
ON : Safety stop state
OFF : Safety circuit fault or RUN/READY
839
22 Mechanical Weakening
Detection
The terminal activates when the drive detects mechanical weakening.
839
2F Maintenance
Notification
The terminal activates when drive components are at their estimated maintenance period.
Tells you about the maintenance period for these items:
• IGBT
• Cooling Fan
• Capacitor
• Soft charge bypass relay
839
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 Selection].
839
31 During Speed Limit
The terminal activates when the speed limit is active.
839
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.
