Error management
Error signalling
If the drive is not ready for operation or if there is an error, the “Ready for operation”
relay output will drop out. The “Error” LED will also turn on. In certain cases, the
“Enable” LED will flash in a particular sequence to indicate an error number for
troubleshooting.
A list of the modes or error states in which the “Ready for operation” relay output drops
out is provided below:
- The drive is in configuration mode
-
The drive is in “idle” mode, “manual movement” mode or “manual movement,
ignore limit sw
itch” mode
-
There is no voltage being supplied to the drive (in this case, the “Error” LED will
not turn on).
- One of the following errors has occurred:
o
Excess heat: The temperature in the drive has risen to over 70°C. In this
case, the drive will continue to move.
o
Analogue input line break: In this case, the drive will behave in line with
the setting “Mode 4: Safe position in the event of a line break”.
o
Motor error (e.g. blockage), see the section “Motor monitoring” below.
o
Error detected in plausib
ility check, see the section “Plausibility check”
below.
o
Position measured at the potentiometer is outside the valid range; the
“Enable” LED will flash twice for troubleshooting.
Motor monitoring
As soon as the motor starts rotating, the drive continuously monitors the speed of the
drive unit and checks for blockages. The drive will attempt to correct any issues itself:
- If the motor is blocked for more than 10 s or if the current speed deviates
significantly from the set speed for more than 10
s, the “Ready for operation”
relay output will drop out and the “Error” LED will turn on.
