Rev. A INSTALLATION & USER’S MANUAL
A list of warnings and faults that should be indicated are detailed in Tables 5.42 and 5.43.
Display Warning Description Drive Reaction
.
Current limiting Active :
Due to: Thermal Foldback, Manual Mode or I
2
t limiting
Current limited
U1 High Power Not Ready – softstart mode. Drive will not enable
U2 Motor Thermal Warning :
This warning indicates that the motor winding temperature is
within 10% of the motor max temperature.
Current limited
U3 Power Amplifier Thermal Warning:
This warning indicates that the power transistor heatsink
temperature is within 10% of the bridge maximum temperature.
Current limited
U4 Regeneration Power Warning :
This warning indicates that the power dissipated in the regen
resistor(s) is within 10% of the continuous capability of the
resistor(s).
None
U5 Position Tracking Warning :
This warning indicates that the position error has exceeded a
pre-set threshold. This error will only be present when the drive
is in position mode.
None
U6 Limit Switch Warning :
This warning indicates that either clockwise or counter clockwise
limit switch has become active.
Cannot move in particular
direction.
U7 24V Backup Supply Warning :
This warning indicates that Logic supply is below 18 Volts, or
greater than 32 Volts.
None
U8 Manual Mode:
This warning indicates that user has switched the drive into
manual mode.
Current and velocity limited to
limman % of normal limits.
U9 Enable Attempted Warning:
This warning indicates that the user has attempted to enable the
drive from a no fault state, but with at least one of the conditions
for enable false (e.g. H/w enable false, Bus voltage not present).
Drive will not enable.
Note that this warning will
remain present once set until
the drive is truly enabled
U10 Power Amplifier Thermal Limit Warning:
This warning indicates that the power transistor heatsink
temperature is causing the current to be limited.
Current limited
U11 Motor Thermal Limit Warning:
This warning indicates that the motor winding temperature is
causing the current to be limited.
Current limited
U12 Ambient Thermal Limit Warning:
This warning indicates that the ambient (control card sensor)
temperature is causing the current to be limited.
Current limited
U13 Ambient Thermal Warning :
This warning indicates that the ambient (control card sensor)
temperature is within 10% of the ambient max temperature.
Current limited
U14 Field Bus Warning:
Set if the firmware and fieldbus card versions are inconsistent.
Drive will not engage
U15 Reserved for future use.
U16 Reserved for future use.
U17 I2T Limit Warning:
Set if the absolute value of current demand pre-thermal limiting
(Field 1122) is greater than or equal to the I2T current limit
(Field 4241) and the drive is enabled.
Current Limited
