180 ● OT DMC-40x0 Command Reference
OT
FUNCTION: Off on encoder failure time
DESCRIPTION:
Sets the time in samples (milliseconds for TM1000) that the controller will wait for motion after
the OV threshold has been exceeded. The controller can detect a failure on either or both
channels of the encoder. This is accomplished by checking on whether motion of at least 4
counts is detected whenever the torque exceeds a preset level (OV) for a specified time (OT).
Note that for this function to work properly it is necessary to have a non-zero value for KI.
ARGUMENTS: OTn,n,n,n,n,n,n,n where
n is the number of samples between 2 and 32000
? returns the last value set
USAGE: DEFAULTS:
While Moving Yes Default Value 30
In a Program Yes Default Format 5.0
Command Line Yes
Controller Usage
ALL CONTROLLERS
OPERAND USAGE:
_OTn contains the OT value for the specified axis.
