AF-600 FP Design and Installation Guide
Possible Cause
Service switch open or missing
motor connection
No line power with 24 V DC
option card
keypad Stop
Missing start signal (Standby)
Motor coast signal active
(Coasting)
Wrong reference signal source
Motor rotation limit
Active reversing signal
Wrong motor phase connection
Frequency limits set wrong
Reference input signal not scaled
correctly
Possible incorrect parameter
settings
Possible over-magnetization
Possible incorrect settings in the
brake parameters. Possible too
short ramp-down times.
Test
Check if the motor is connected
and the connection is not
interrupted (by a service switch or
other device).
If the display is functioning but no
output, check that line power is
applied to the adjustable frequency
drive.
Check if [Off] has been pressed.
Check E-01 Terminal 18 Digital Input
for correct setting for terminal 18
(use default setting).
Check if a coast inv command is
programmed for the terminal in
parameter group E-0# Digital
Inputs
Check reference signal: Local,
remote or bus reference? Preset
reference active? Terminal
connection correct? Scaling of
terminals correct? Reference signal
available?
Check that H-08 Reverse Lock is
programmed correctly.
Check if a reversing command is
programmed for the terminal in
parameter group E-0# Digital inputs.
Check output limits in F-17 Motor
Speed High Limit [RPM], F-15 Motor
Speed High Limit [Hz] and F-03 Max
Output Frequency 1
Check reference input signal
scaling in AN-## Reference limits in
parameter group F-5#.
Check the settings of all motor
parameters, including all motor
compensation settings. For closed-
loop operation, check PID settings.
Check for incorrect motor settings
in all motor parameters.
Check brake parameters. Check
ramp time settings.
DET-768A
Solution
Connect the motor and check the
service switch.
Apply line power to run the unit.
Press [Auto] or [Hand] (depending
on operation mode) to run the
motor.
Apply a valid start signal to start
the motor.
Apply 24 V on terminal or program
this terminal to No operation.
Program correct settings. Check
F-02 Operation Method. Set preset
reference active in parameter
C-05 Multi-step Frequency 1 - 8 .
Check for correct wiring. Check
scaling of terminals. Check
reference signal.
Program correct settings.
Deactivate reversing signal.
See 3.5 Check Motor Rotation in this
manual.
Program correct limits.
Program correct settings.
Check settings in parameter group
AN-##. For closed-loop operation,
check settings in parameter group
CL-0#
Check motor settings in parameter
groups P-0# Motor Data, P-3# Adv
Motor Data, and H-5# Load Indep.
Setting.
Check parameter group B-0# DC
brake and F-5# Extended Reference.
