9.10 H: Terminal Functions
622 YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference
Setting Value Function Description Ref.
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
287
1E Executing Auto-Restart The terminal activates when the Auto Restart function is trying to restart after a fault. 287
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.
287
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]. 287
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
287
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
288
37 During Frequency Output The terminal activates when the drive outputs frequency.
ON : The drive outputs frequency.
OFF : The drive does not output frequency.
288
38 Drive Enabled This terminal activates when the H1-xx = 6A [Drive Enable] terminal activates. 288
39 Watt Hour Pulse Output Outputs the pulse that shows the watt hours. 288
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.
289
3D During Speed Search The terminal activates when the drive is doing speed search. 289
42 Pressure Reached The terminal activates when the drive is at the Pressure Setpoint. 289
4C During Fast Stop The terminal activates when the fast stop is in operation. 289
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.
289
51 Sequence Timer 1 The terminal activates when Sequence Timer 1 is active. 289
52 Sequence Timer 2 The terminal activates when Sequence Timer 2 is active. 289
53 Sequence Timer 3 The terminal activates when Sequence Timer 3 is active. 290
54 Sequence Timer 4 The terminal activates when Sequence Timer 4 is active. 290
58 UL6 Underload Detected The terminal activates when the drive detected UL6 [Underload or Belt Break Detected]. 290
60 Internal Cooling Fan
Failure
The terminal activates when the drive detects a cooling fan failure in the drive. 290
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.
290
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.
290
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.
290
6A Data Logger Error The terminal activates when the drive detects LoG [Com Error / Abnormal SD card]. 290
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]. 290
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]. 290
89 Output Current Lim The terminal activates when the output current limit is limiting the drive output speed. 291
94 Loss of Prime The terminal activates when the drive is in an LOP [Loss of Prime] condition. 291
95 Thermostat Fault The terminal activates when the terminal set for H1-xx = 88 [MFDI Function Selection = Thermostat Fault] is active. 291
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.
