Pulse reference inputs
Terminate pulse reference inputs at the Drive by connecting across the
related input terminals a resistor whose value equals the characteristic
impedance of the cable that is being used. When more than one Drive is
connected to a pulse reference link, a terminating resistor is required
only at the last Drive on the link.
