2.8 H: Terminal Functions
400 YASKAWA TOEPYAIGA8002B GA800 Drive Programming
OFF : Safety circuit fault or RUN/READY
Terminal H1-HC or terminal H2-HC is OFF (Open) (safety circuit fault), or the two terminals are ON or have short
circuited (RUN/READY).
■ 22: Mechanical Weakening Detection
Setting Value Function Description
22 Mechanical Weakening
Detection
The terminal activates when the drive detects mechanical weakening.
Note:
Refer to “Mechanical Weakening Detection Function” for more information.
■ 2F: Maintenance Notification
Setting Value Function Description
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
Note:
Refer to “Alarm Outputs for Maintenance Monitors” for more information.
■ 30: During Torque Limit
Setting Value Function Description
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].
Note:
Refer to “L7: Torque Limit” for more information.
■ 31: During Speed Limit
Setting Value Function Description
31 During Speed Limit
The terminal activates when the speed limit is active.
The speed limit activates and the terminal activates in these conditions:
• The frequency reference ≥ d2-01 [Frequency Reference Upper Limit]
• The frequency reference ≤ d2-02 [Frequency Reference Lower Limit] or d2-03 [Analog Frequency Ref Lower
Limit].
• The frequency reference ≤ E1-09 [Minimum Output Frequency] when b1-05 = 1, 2, or 3 [Operation Below
Minimum Freq = Baseblock (Motor Coasts), Operate at Minimum Frequency, or Operate at Zero Speed].
• The frequency reference ≤ Output Freq Lower Limit Level [H3-xx = 9] through analog input.
■ 32: In Speed Limit During Trq Ctrl
Setting Value Function Description
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.
Note:
Refer to “d5-03: Speed Limit Selection” for more information.
