Code Name
Note:
• The drive detects this error if the DC bus voltage changes irregularly without regeneration.
• If the drive detects this error, the terminal set to H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm] will activate.
• Use L8-05 [Input Phase Loss Protection Sel] to enable and disable PF detection.
Code Name
SAFE Safety Open
Code Name
SAFE Customer Safeties
Note:
• If the terminal set for H1-xx = B1 [MFDI Function Selection = Customer Safeties] deactivates, the drive detects this alarm.
• If the drive detects this error, the terminal set to H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm] will activate.
• This alarm has display priority over INTLK [BAS Interlock].
Code Name
SE Modbus Test Mode Error
Note:
If drive detects this error, the terminal set to H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm] will activate.
Code Name
SMK_ALRM Smoke Alarm Active
Code Name
STo Safe Torque OFF
Note:
• The drive will not output an alarm signal for this alarm.
• If the drive detects this error, the terminal set to H2-01 to H2-03 = 21 [MFDO Function Selection = Safe Torque OFF] will activate.
Code Name

Note:
If the drive detects this error, the terminal set to H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm] will activate.
Code Name
TiM Keypad Time Not Set
Note:
• Parameter o4-24 [bAT Detection selection] enables and disables TiM detection.
• If the drive detects this error, the terminal set to H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm] will activate.
YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference
Causes
The main circuit capacitors are unserviceable.
Causes
The bypass received a Run command when a safety
was open.
Causes
External contact from customer wiring is open.
Causes
MEMOBUS/Modbus communications self-
diagnostics [H1-xx = 67] was done while the drive
was running.
Causes
The bypass detected a Smoke Alarm condition.
Causes
Safe Disable inputs H1-HC and H2-HC are open.
There is internal damage to the two Safe Disable
channels.
Causes
One of the two terminals H1-HC or H2-HC received
the Safe Disable input signal.
The Safe Disable input signal is wired incorrectly.
There is internal damage to one Safe Disable channel.
Causes
There is a battery in the keypad, but you have not set
the date and time.
6.6 Minor Faults/Alarms
Possible Solutions
• Examine the capacitor maintenance time in monitor U4-05
[CapacitorMaintenance].
• If U4-05 is more than 90%, replace the capacitor. Contact
Yaskawa or your nearest sales representative for more
information.
• Examine the input power for problems.
• Re-energize the drive.
• If the alarm stays, replace the circuit board or the drive. Contact
Yaskawa or your nearest sales representative for more
information.
Possible Solutions
Remove the cause of the open safety.
Possible Solutions
Examine the cause of the open safety.
Possible Solutions
Stop the drive and do MEMOBUS/Modbus communications self-
diagnostics.
Possible Solutions
• Check the digital input programmed for Smoke Alarm (Z2-0x =
40).
• Check the connected device for continuity.
• Check Bypass Digital Input Invert Settings in Z2-09 to Z2-16.
Possible Solutions
• Make sure that the Safe Disable signal is input from an external
source to terminal H1-HC and H2-HC.
• When the Safe Disable function is not in use, use a jumper to
connect terminals H1-HC and H2-HC.
Replace the board or the drive. Contact Yaskawa or your nearest
sales representative to replace the board.
Possible Solutions
• Make sure that the Safe Disable signal is input from an external
source to terminals H1-HC or H2-HC.
• When the Safe Disable function is not in use, use a jumper to
connect terminals H1-HC and H2-HC.
Replace the board or the drive. Contact Yaskawa or your nearest
sales representative to replace the board.
Possible Solutions
Use the keypad to set the date and time.
