DIO CN1-11 to 18
P.IN0 to 7 Point selection / Position data
j Point Selection 0 to 6 [UP-01 (Control Mode) = 11 or 12]
This is the signal input for selecting positioning data from PTP data.
The range of data is 1 to 64, in BCD.
Point selections 0 to 3 become the data input for digit 10
1
input for digit 10 .
Example: When point No. 12 is set.
Point selection
j Positions 0 to 7 [UP-01 (Control Mode) = 13 or 14]
This is the positioning data signal input.
The range of data is 0 to 99, in BCD (up to a maximum of "F9," for the position's leftmost digits only).
The 32 bits for the position data and the 8 bits for the speed data are taken eight bits at a time. At this
time the position and speed selection signals (P.OUT 0 to 4) are output as data request signals. Re-
fresh the input data according to the data request signals.
If the speed is set to "0," it will be taken as 100%.
DIO CN1-20
STOP Deceleration stop
This is the signal input for forcibly stopping motor rotation.
While this signal is not being input (ON), the motor cannot be driven.
With the CompoBus/S Position Drivers, the motor cannot be driven unless the external control signal
input (CN4-4) and the CompoBus/S input (OUT7) are both input.
The method for stopping the motor depends on the set value for PP-24 (deceleration stop mode).

DIO CN1-21
BO Brake output
When UP-16 (brake mode) is set to 1, 2, or 3 (brake retention), the timing signal for applying the elec-
tromagnetic brake is output. If the motor's rotation speed falls below the UP-28 (brake-ON r/min) set
value under the following circumstances, the output will be turned OFF and the electromagnetic brake
will be operated.
When the RUN signal has been turned OFF.
When an error shutting OFF the power to the motor has occurred.
When a deceleration stop turns OFF while PP-24 (deceleration stop mode) is set to 0 (free-run
stop).
When UP-16 is set to 0 (dynamic brake), the timing signal for applying the dynamic brake is output.
Under the following circumstances the output is turned OFF and the dynamic brake is operated.
