VLT® Decentral Drive FCD 302
Operating Guide
•
[14] Jog was selected as a function for a digital input (parameter group 5-1* Digital Inputs). The corresponding
terminal (for example, terminal 29) is active.
• The jog function is activated via the serial communication.
• The jog function is selected as a reaction for a monitoring function (for example, for the no signal function).
The monitoring function is active.
Motor check
In parameter 1-80 Function at Stop, [2] Motor Check is selected. A stop command is active. To ensure that a motor is
connected to the drive, a permanent test current is applied to the motor.
OVC control Overvoltage control is activated via parameter 2-17 Over-voltage Control, [2] Enabled. The connected motor sup-
plies the drive with generative energy. The overvoltage control adjusts the V/Hz ratio to run the motor in control-
led mode and to prevent the drive from tripping.
PowerUnit (Only drives with a 24 V external supply installed). Mains supply to the drive was removed, and the control card is
Off supplied by the external 24 V.
Protection
Protection mode is active. The unit detected a critical status (overcurrent or overvoltage).
md
• To avoid tripping, switching frequency is reduced to 4 kHz.
• If possible, protection mode ends after approximately 10 s.
• Protection mode can be restricted in parameter 14-26 Trip Delay at Inverter Fault.
QStop
The motor is decelerating using parameter 3-81 Quick Stop Ramp Time.
• [4] Quick stop inverse is selected as a function for a digital input (parameter group 5-1* Digital Inputs). The corre-
sponding terminal is not active.
• The quick stop function is 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 parameter 4-55 Warning Reference High.
Ref. low The sum of all active references is below the reference limit set in parameter 4-54 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 was given, but the motor remains stopped until a run permissive signal is received via digital
input.
Running The drive drives the motor.
Sleep Mode The energy-saving function is enabled. The motor has stopped, but restarts automatically when required.
Speed high
Motor speed is above the value set in parameter 4-53 Warning Speed High.
Speed low
Motor speed is below the value set in parameter 4-52 Warning Speed Low.
Standby
In auto-on mode, the drive starts the motor with a start signal from a digital input or serial communication.
Start delay In parameter 1-71 Start Delay, a delay starting time was set. A start command is activated, and the motor starts
after the start delay time expires.
Start
[12] Enable start forward and [13] Enable start reverse are selected as options for 2 different digital inputs (parame-
fwd/rev
ter group 5-1* Digital Inputs). The motor starts in forward or reverse direction depending on which terminal is acti-
vated.
Stop
The drive received a stop command from the LCP, digital input, or serial communication.
