Description
The MDT Blanking Period parameter specifies the amount of time that the MDT input waits after the start pulse before looking for the stop pulse. This parameter is valid only on RMC150 and RMC200 axes with MDT feedback.
Typically, this parameter should be left at its default setting. For older Temposonics I and II transducers with a neuter output, this parameter needs to be set to 21µs, since the start pulses contain ringing that lasts longer then the default 5µs.
The RMC75 blanking period is fixed at 5µsec. Transducers that require the longer 21µsec blanking period will require using the RMC150 or RMC200.
Changing this Parameter
Because this parameter affects motion, the axis must be disabled or in Direct Output before writing to this parameter. The Enabled and Direct OutputStatus Bits indicate these states of the axis. When changing this parameter from RMCTools, the software will automatically do this for you. This may cause a halt on the axis, which is expected.
See the SSI/MDT Configuration Register for details about the register containing these bits.
