ten DI terminals.

Note

Only DI5 is allowed to receive high-speed pulse signals. If your application uses

high-speed pulse counts, then you must use DI5 for this input.

Filter Time and Delay Functions

F4-10 sets a filter time on the DI signal to improve performance of the drive in conditions of

strong electrical interference.

The drive also provides a signal delay function on digital inputs DI1 to DI3 to support some

applications that require a delayed digital input. You can set the delay separately for each of the

three DI terminals:

Function code F4-35 controls the delay on DI1.

Function code F4-36 controls the delay on DI2.

Function code F4-37 controls the delay on DI3.

Use of DO Terminals

There are three digital output terminals on control board:

FM is a transistor output capable of driving a 24 V DC low-voltage circuit.

DO1 is a transistor output capable of driving a 24 V DC low-voltage circuit.

TA/TB/TC is a relay output that can drive a 250 V AC control circuit.

There are two additional digital outputs on the optional I/O extension board, which are available

to use if you have this option installed.

DO2 s a transistor output capable of driving a 24 V DC low-voltage circuit.

PA/PB/PC is a relay output that can drive a 250 V AC control circuit.
