GE Industrial Solutions AF-600 FP Fan & Pump Drive (230V to 60HP, 460_575V to 125HP) - Manual (Page 50)

Operation Status
DC Hold DC hold is selected in H-80 Function at Stop
and a stop command is active. The motor is
held by a DC current set in B-00 DC Hold
Current.
DC Stop The motor is held with a DC current (B-01 DC
Brake Current) for a specified time (B-02 DC
Braking Time).
• DC Brake is activated in B-03 DC Brake Cut
In Speed [RPM] and a Stop command is
active.
• DC Brake (inverse) is selected as a function
for a digital input. The corresponding
terminal is not active.
• The DC Brake is activated via serial
communication.
Feedback high The sum of all active feedbacks is above the
feedback limit set in H-77 Warning Feedback
High.
Feedback low The sum of all active feedbacks is below the
feedback limit set in H-76 Warning Feedback
Low.
Freeze output The remote reference is active which holds
the present speed.
• Freeze output was selected as a function
for a digital input. The corresponding
terminal is active. Speed control is only
possible via the terminal functions speed
up and speed down.
• Hold ramp is activated via serial communi-
cation.
Freeze output
request
A freeze output command has been given,
but the motor will remain stopped until a run
permissive signal is received.
Freeze ref. Freeze Reference was chosen as a function for
a digital input. The corresponding terminal is
active. The drive saves the actual reference.
Changing the reference is now only possible
via terminal functions speed up and speed
down.
Jog request A jog command has been given, but the
motor will be stopped until a run permissive
signal is received via a digital input.
Jogging The motor is running as programmed in
C-21 Jog Speed [RPM].
• Jog was selected as function for a digital
input. The corresponding terminal (e.g.
Terminal 29) is active.
• The Jog function is activated via the serial
communication.
• The Jog function was selected as a
reaction for a monitoring function (e.g. No
signal). The monitoring function is active.
Operation Status
OVC control Overvoltage control was activated in B-17 Over-
voltage Control. The connected motor is
supplying the drive with generative energy.
The overvoltage control adjusts the V/Hz ratio
to run the motor in controlled mode and to
prevent the drive from tripping.
PowerUnit Off (For frequency converters with an external 24V
power supply installed only.) Mains supply to
the drive is removed, but the control card is
supplied by the external 24V.
Protection md Protection mode is active. The unit has
detected a critical status (an overcurrent or
overvoltage).
• To avoid tripping, switching frequency is
reduced to 4kHz.
• If possible, protection mode ends after
approximately 10sec.
• Protection mode can be restricted in
SP-26 Trip Delay at Drive Fault
QStop The motor is decelerating using C-23 Quick
Stop Decel Time.
• Quick stop inverse was chosen as a function
for a digital input. The corresponding
terminal is not active.
• The quick stop function was activated via
serial communication.
Ramping The motor is accelerating/decelerating using
the active Ramp Up/Down. The reference, a
limit value or a standstill is not yet reached.
Ref. high The sum of all active references is above the
reference limit set in H-75 Warning Reference
High.
Ref. low The sum of all active references is below the
reference limit set in H-74 Warning Reference
Low .
Run on ref. The drive is running in the reference range.
The feedback value matches the setpoint
value.
Run request A start command has been given, but the
motor is stopped until a run permissive signal
is received via digital input.
Running The motor is driven by the drive.
Sleep Mode The energy saving function is enabled. This
means that at present the motor has stopped,
but that it will restart automatically when
required.
Speed high Motor speed is above the value set in
H-73 Warning Speed High.
Speed low Motor speed is below the value set in
H-72 Warning Speed Low.
Standby In Auto mode, the drive will start the motor
with a start signal from a digital input or serial
communication.
