Fault
possible causes
measures to remove the cause of the fault
message:
feedback unit
—
feedback connector not properly inserted
—
feedback cable is broken, crushed or
otherwise damaged
—
check connector
—
check cable
message:
internal temperature
—
permissible internal temperature exceeded —
improve ventilation
Message:
motor temperature
—
motor thermostat has been activated
—
feedback connector is loose or break in
feedback cable
—
wait till motor has cooled down, then
check why it became so hot
—
screw connector up tight or use new
feedback cable
motor does not
rotate
—
servo amplifier not enabled
—
break in setpoint cable
—
motor phases swapped
—
brake not released
—
drive is mechanically blocked
—
motor palr no. set incorrectly
—
feedback set up incorrectly
—
apply enable signal
—
check setpoint cable
—
correct motor phase sequence
—
check brake control
—
check mechanism
—
set motor pole no.
—
set up feedback correctly
motor runs away
(overspeed)
—
motor phases swapped
—
feedback set up incorrectly
—
correct motor phase sequence
—
set up correct offset angle
motor oscillates
—
gain too high (speed controller)
—
shielding in feedback cable has a break
—
AGND not wired up
—
reduce Kp (speed controller)
—
replace feedback cable
—
join AGND to CNC-GND
drive reports
following error
—
I
rms
or I
peak
is set to low
—
setpoint ramp is too long
—
increase I
rms
or I
peak
(keep within motor data !)
—
shorten setpoint ramp +/-
motor overheating
—
I
rms
/I
peak
set too high
—
reduce I
rms
/I
peak
drive too soft
—
Kp (speed controller) too low
—
Tn (speed controller) too high
—
PID-T2 too high
—
T-Tacho too high
—
increase Kp (speed controller)
—
use motor default value for
Tn (speed controller)
—
reduce PID-T2
—
reduce T-Tacho
drive runs
roughly
—
Kp (speed controller) too high
—
Tn (speed controller) too low
—
PID-T2 too low
—
T-Tacho too low
—
reduce Kp (speed controller)
—
use motor default value for
Tn (speed controller)
—
increase PID-T2
—
increase T-Tacho
axis drifts at
setpoint = 0V
—
offset not correctly adjusted for analog
setpoint provision
—
AGND not joined to the CNC-GN of the
controls
—
adjust setpoint-offset (analog I/O)
—
join AGND and CNC-GND
