Cause
Solution
Communication and Control Issues
Motor control power
light does not illu-
minate.
Control power is off, dis-
connected or incorrectly
wired.
Check that control power is connected to
the proper pins and turned on. For con-
nection details, see Connecting the Sys-
tem on page 30.
Motor does not com-
municate with SMI.
Transmit, receive or
ground pins are not con-
nected correctly.
Ensure that transmit, receive and ground
are all connected properly to the host PC.
Motor program is stuck
in a continuous loop or
is disabling com-
munications.
To prevent the program from running on
power up, use the Communications
Lockup Wizard located on the SMI soft-
ware Communications menu.
Motor disconnects
from SMI sporad-
ically.
COM port buffer settings
are too high.
Adjust the COM port buffer settings to
their lowest values.
Poor connection on
serial cable.
Check the serial cable connections and/or
replace it.
Power supply unit (PSU)
brownout.
PSU may be too high-precision and/or
undersized for the application, which
causes it to brown-out during motion.
Make moves less aggressive, increase
PSU size or change to a linear unreg-
ulated power supply.
Motor stops com-
municating after
power reset, requires
re-detection.
Motor does not have its
address set in the user
program. NOTE: Serial
addresses are lost when
motor power is off or
reset.
Use the SADDR or ADDR= command
within the program to set the motor
address.
Red PWR SERVO light
illuminated.
Critical fault.
To discover the source of the fault, use
the Motor View tool located on the SMI
software Tools menu.
Common Faults
Bus voltage fault.
Bus voltage is either too
high or too low for oper-
ation.
Check servo bus voltage. If motor uses
the DE power option, ensure that both
drive and control power are connected.
Overcurrent
occurred.
Motor intermittently
drew more than its
rated level of current.
Does not cease motion.
Consider making motion less abrupt with
softer tuning parameters or acceleration
profiles.
