9.3 Fault Monitoring System
The SERVOSTAR’s microprocessor is constantly monitoring the
status of many different components. In general, the philosophy of
the SERVO
STAR is to latch all fault conditions so you can readily
determine the source of the problem. When a fault is detected, it is
logged in the internal error log, indicated in the Status Display,
enunciated over the serial port, and in most conditions causes a
drive disable. Many faults are reset by toggling the hardware
remote enable (REMOTE input).
The following provides a list of some of the more frequent faults the
drive may detect in the unit hardware and operating system.
Motor OverTemperature
The motor’s external thermostat input is monitored for an open
circuit condition. You can define (using THERMODE) what happens
under this fault condition. The worst-case event is a power stage
disable when an ‘H’ appears in the status display, and the fault
relay contacts (RELAY) are open.
Hardware Position Limit Inputs
The IN1, IN2, IN3 Inputs are constantly monitored. If INxMODE
sets these inputs for CW/CCW hardware position limits, they are
monitored for an open-circuit condition. Although not necessarily an
error condition, motor operation can be affected by these inputs.
The SERVO
STAR can ignore the hardware position limits if you set
LIMDIS = 1. The worst-case event is that further motion in the given
direction is not allowed with an ‘L’ illuminated in the status display.
If both CW and CCW position limit inputs have detected an open-
circuit condition, the SERVO
STAR enters into Hold position state
(HOLD = 1).
Drive OverTemperature
The internal heatsink temperature is monitored for an unsafe
condition. This condition causes a ‘t’ to be displayed and disables
the drive. The drive will eventually cool enough to allow reset of this
condition.
RMS OverCurrent (FoldBack)
The FoldBack detection system can restrict the available output
current. This is not a true fault condition, but may cause undesired
performance, due to the command current being limited below what
is required to achieve the desired performance. This condition is
indicated with a flashing F in the status display and can be detected
by monitoring the FOLD switch variable.
