Description
Parameter upload or download failed. The software versions of the drives may
not be compatible. Software version can be seen from parameter 3301
.
SOFTWARE VERSION
Control panel function is not allowed while start is active.
Control panel function is not allowed in current control mode (local or remote).
Control mode is local when LOC is displayed and remote mode when REM is
displayed on the control panel.
Control panel function is denied for any of the following reasons:
• START/STOP button is interlocked from digital input. This can happen with
certain digital input configurations. Refer to chapter Application Macros.
• REVERSE button is locked because shaft direction is fixed by parameter
1003 .
DIRECTION
• The drive is in remote control mode and START/STOP and REVERSE
buttons are not followed.
Control panel function is not allowed:
• Parameter 1602
PARAMETER LOCK
• Parameter 1605
LOCAL LOCK
Control panel function is not allowed: Factory macro is selected and denies the
parameter modifications. Factory macro is intended for applications where
there is no control panel available.
Overcurrent controller is active.
Overvoltage controller is active.
Undervoltage controller is active.
Rotation direction if fixed by parameter 1003
Serial communication through Standard Modbus Channel is lost.
• Check connections between external control system and the ACS 400.
• Refer to parameters 5003
Exception response is sent through Standard Modbus channel. The bus master
may be sending queries which cannot be processed by the ACS 400. Refer to
"Standard Serial Communication" section.
Last three exception response codes are stored into parameters 5213 - 5215.

Panel communication loss. Control panel is disconnected when
- Drive is in local control mode (LOC is shown in the control panel display), or
- Drive is in remote control mode (REM) and is parameterised to accept start/
stop, direction or reference from the panel. Refer to parameters in groups 10
COMMAND INPUTS and 11 REFERENCE SELECT.

ACS 400 overtemperature condition. This alarm is given when the temperature
reaches 95% of the trip limit.
Motor overtemperature condition as estimated by the ACS 400. Refer to
parameters 3004 – 3008.
Motor load is too low. Check for a problem in the driven equipment. Refer to
parameters 3013 – 3015.
Motor is operating in the stall region. This may be caused by excessive load or
insufficient motor power. Refer to parameters 3009 – 3012.
