7.8 H: Terminal Functions
YASKAWA TOEPYAIH6B01A HV600 AC Drive Narrow Bypass Installation & Startup 201
Setting Value Function Description
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
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
37 During Frequency Output The terminal activates when the drive outputs frequency.
ON : The drive outputs frequency.
OFF : The drive does not output frequency.
38 Drive Enabled This terminal activates when the H1-xx = 6A [Drive Enable] terminal activates.
39 Watt Hour Pulse Output Outputs the pulse that shows the watt hours.
3A Drive Overheat Alarm The terminal activates when the drive heatsink temperature is at the L8-02 [Overheat Alarm Level] setting while L8-03 = 4
[Overheat Pre-Alarm Selection = Operate at Reduced Speed (L8-19)] and the drive is running.
3D During Speed Search The terminal activates when the drive is doing speed search.
42 Pressure Reached The terminal activates when the drive is at the Pressure Setpoint.
4C During Fast Stop The terminal activates when the fast stop is in operation.
4D oH Pre-Alarm Reduction
Limit
The terminal activates when L8-03 = 4 [Overheat Pre-Alarm Selection = Operate at Reduced Speed (L8-19)] and oH [Heatsink
Overheat] does not clear after the drive decreases the frequency for 10 cycles.
51 Sequence Timer 1 The terminal activates when Sequence Timer 1 is active.
52 Sequence Timer 2 The terminal activates when Sequence Timer 2 is active.
53 Sequence Timer 3 The terminal activates when Sequence Timer 3 is active.
54 Sequence Timer 4 The terminal activates when Sequence Timer 4 is active.
58 UL6 Underload Detected The terminal activates when the drive detected UL6 [Underload or Belt Break Detected].
60 Internal Cooling Fan Failure The terminal activates when the drive detects a cooling fan failure in the drive.
62 Modbus Reg 1 Status
Satisfied
The terminal activates when the bit specified by H2-08 [Modbus Register 1 Bit Select] for the MEMOBUS register address set with
H2-07 [Modbus Register 1 Address Select] activates.
63 Modbus Reg 2 Status
Satisfied
The terminal activates when the bit specified by H2-10 [Modbus Register 2 Bit Select] for the MEMOBUS register address set with
H2-09 [Modbus Register 2 Address Select] activates.
69 External Power 24V Supply The terminal activates when there is an external 24V power supply between terminals PS-AC.
ON : An external 24V power supply supplies power.
OFF : An external 24V power supply does not supply power.
6A Data Logger Error The terminal activates when the drive detects LoG [Com Error / Abnormal SD card].
71 Low PI2 Control Feedback
Level
The terminal activates when the PI2 Control Feedback Level is less than S3-13 [PI2 Control Low Feedback Lvl].
72 High PI2 Control Feedback
Level
The terminal activates when the PI2 Control Feedback Level is more than S3-15 [PI2 Control High Feedback Lvl].
89 Output Current Lim The terminal activates when the output current limit is limiting the drive output speed.
94 Loss of Prime The terminal activates when the drive is in an LOP [Loss of Prime] condition.
95 Thermostat Fault The terminal activates when the terminal set for H1-xx = 88 [MFDI Function Selection = Thermostat Fault] is active.
96 High Feedback The terminal activates when the drive is in a High Feedback Condition as specified by Y1-11 [High Feedback Level] and Y1-12
[High Feedback Lvl Fault Dly Time] and when the drive detects an HFB [High Feedback Sensed] fault or an HIFB [High Feedback
Sensed] alarm.
97 Low Feedback The terminal activates when the drive is in a Low Feedback Condition as specified by Y1-08 [Low Feedback Level] and Y1-09 [Low
Feedback Lvl Fault Dly Time] and when the drive detects an LFB [Low Feedback Sensed] fault or an LOFB [High Feedback
Sensed] alarm.
9E Low PI Auxiliary Control
Level
The terminal activates when the PI Aux Feedback Level is less than YF-09 [PI Aux Control Low Level Detect] or if the drive detects
an LOAUX [Low PI Aux Feedback Level] fault.
9F High PI Auxiliary Control
Level
The terminal activates when the PI Aux Feedback Level is more than YF-12 [PI Aux Control High Level Detect] or if the drive
detects an HIAUX [High PI Aux Feedback Level] fault.
A9 RELAY Operator Control
The terminal changes to OFF or ON when you push the RELAY ( ) button. When the terminal is ON, push to turn
it OFF. When the terminal is OFF, push to turn in ON.
