QStop
The motor is decelerating using 3–81 Quick Stop Ramp
Time.
• Quick stop inverse was chosen as a function for a
digital input (parameter group 5–1* Digital Inputs).
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 4–55 Warning Reference High.
Ref. low
The sum of all active references is below the reference
limit set in 4–54 Warning Reference Low.
Run on ref.
The controller is running in the reference range. The
feedback value matches the setpoint value.
Run request
A start commend 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 controller.
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 4–53 Waning
Speed High.
Speed low
Motor speed below the value set in 4–52 Warning Speed
Low.
Standby
In Auto On mode, the controller will start the motor with
a start signal from a digital input or serial
communication.
Start delay
In 1–71 Start Delay, a delay starting time was set. A start
command is activated and the motor will start after the
start delay time expires.
Start fwd/rev
Start forward and start reverse were selected as functions
for two different digital inputs (parameter group 5–1*
Digital Inputs). The motor will start in forward or reverse
depending on which corresponding terminal is activated.
Stop
The controller has received a stop command from the
LCP, digital input or serial communication.
Trip
An alarm occurred and the motor is stopped. Once the
cause of the alarm is cleared, the controller can be reset
manually by pressing [Reset] or remotely by control
terminals or serial communication.
Trip lock
An alarm occurred and the motor is stopped. Once the
cause of the alarm is cleared, power must be cycled to the
controller. The controller can then be reset manually by
pressing [Reset] or remotely by control terminals or serial
communication.
LCP parameters
The display configuration shown above represents the default settings. Items 2-6 can be
adjusted to display other values. To display other values, modify parameters 0-20, 0-21,
0-22, 0-23 or 0-24 which correspond to 2, 3, 4, 5 and 6 respectively.
