Ud A Command up / down setting will increase or decrease the
present value with each counter 1 input signal depending on if
counter 2 input is engaged. When counter 2 input is engaged, each
counter 1 input signal will decrease the count.
Ud b Individual up / down setting will increase the present value with
each counter 1 input signal and decrease with each counter 2 input
signal.
Ud C Quadrature up / down uses the order of the inputs to determine
whether to count up or down. If counter input 1 leads counter input
2, the unit will count up. If counter input 2 leads counter input 1, the
unit will count down.
