| Off on encoder failure voltage | |||
Sets the threshold voltage for detecting an encoder failure. 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.
The default value for OV is approximately .95 volts. The value should be high enough to guarantee that the motor would overcome any static friction. If it is too low, there will be false triggering of the error condition. The OV value may not be higher than the TL value.
OV n,n,n,n,n,n,n,n where
where n is a positive voltage between 0.001 and 9.9 volts.
? returns the last value set
_OVn contains the OV value for the specified axis.
