204 YASKAWA TOEPYAIH6B01A HV600 AC Drive Narrow Bypass Installation & Startup
Setting Value Function Description
11F !Motor Overload Alarm
(oL1)
The terminal deactivates when the electronic thermal protection value of the motor overload protective function is a minimum of
90% of the detection level.
120 !Drive Overheat Pre-Alarm
(oH)
The terminal deactivates when the drive heatsink temperature is at the level set with L8-02 [Overheat Alarm Level].
121 !Safe Torque OFF The terminal deactivates (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 circuit fault or RUN/READY
OFF : Safety stop state
12F !Maintenance Notification The terminal deactivates 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
137 !During Frequency Output The terminal deactivates when the drive outputs frequency.
ON : The drive does not output frequency.
OFF : The drive outputs frequency.
138 !Drive Enabled This terminal deactivates when the H1-xx = 6A [Drive Enable] terminal deactivates.
139 !Watt Hour Pulse Output Outputs the pulse that shows the watt hours.
13A !Drive Overheat Alarm The terminal deactivates 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.
13D !During Speed Search The terminal deactivates when the drive is doing speed search.
142 !Pressure Reached The terminal deactivates when the drive is at the Pressure Setpoint.
14C !During Fast Stop The terminal deactivates when the fast stop is in operation.
14D !oH Pre-Alarm Reduction
Limit
The terminal deactivates 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.
151 !Sequence Timer 1 The terminal deactivates when Sequence Timer 1 is active.
152 !Sequence Timer 2 The terminal deactivates when Sequence Timer 2 is active.
153 !Sequence Timer 3 The terminal deactivates when Sequence Timer 3 is active.
154 !Sequence Timer 4 The terminal deactivates when Sequence Timer 4 is active.
158 !UL6 Underload Detected The terminal deactivates when the drive detected UL6 [Underload or Belt Break Detected].
160 !Internal Cooling Fan Failure The terminal deactivates when the drive detects a cooling fan failure in the drive.
162 !Modbus Reg 1 Status
Satisfied
The terminal deactivates 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.
163 !Modbus Reg 2 Status
Satisfied
The terminal deactivates 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.
169 !External Power 24V Supply The terminal deactivates when there is an external 24V power supply between terminals PS-AC.
ON : An external 24V power supply does not supply power.
OFF : An external 24V power supply supplies power.
16A !Data Logger Error The terminal deactivates when the drive detects LoG [Com Error / Abnormal SD card].
171 !Low PI2 Control Feedback
Level
The terminal deactivates when the PI2 Control Feedback Level is less than S3-13 [PI2 Control Low Feedback Lvl].
172 !High PI2 Control Feedback
Level
The terminal deactivates when the PI2 Control Feedback Level is more than S3-15 [PI2 Control High Feedback Lvl].
189 !Output Current Lim The terminal deactivates when the output current limit is limiting the drive output speed.
194 !Loss of Prime The terminal deactivates when the drive is in an LOP [Loss of Prime] condition.
195 !Thermostat Fault The terminal deactivates when the terminal set for H1-xx = 88 [MFDI Function Selection = Thermostat Fault] is active.
196 !High Feedback The terminal deactivates 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.
197 !Low Feedback The terminal deactivates 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.
19E !Low PI Auxiliary Control
Level
The terminal deactivates 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.
