START ACTIVE Control panel function is not allowed while start is active.
3 *
LOCAL/REMOTE 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.
5 *
BUTTON DISABLED 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 section on 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.
6 *
PARAM/LOCAL LOCK Control panel function is not allowed:
• Parameter 1602
PARAMETER LOCK denies parameter editing
• Parameter 1605
LOCAL LOCK denies local control mode.
7 *
FACTORY MACRO 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.
10 **
OVERCURRENT Overcurrent controller is active.
11 **
OVERVOLTAGE Overvoltage controller is active.
12 **
DC UNDERVOLTAGE Undervoltage controller is active.
13
DIRECTION LOCK Rotation direction if fixed by parameter 1003 DIRECTION.
14
SERIAL COMM LOSS Serial communication through Standard Modbus Channel is lost.
• Check connections between external control system and the ACS 160.
• Refer to parameters 5204
COMM FAULT TIME and 5205 COMM FAULT FUNC.

MOTOR OVERTEMP Motor overtemperature condition as estimated by the ACS 160. Refer to
parameters 3004 – 3008.
21
UNDERLOAD Motor load is too low. Check for a problem in the driven equipment. Refer to
parameters 3013 – 3015.
