AI1+ 
Analog input 1 0 - 10 V Voltage speed reference (programmable to 4 mA to 20 mA).
9 AI1- Analog input 1 ground — Analog input 1 common (ground).
10 GND I/O signal ground — I/O ground for reference and control.
11 AO1+ Analog output 1 Output frequency Shows output frequency to motor 0 - 60 Hz (4 mA to 20 mA).
12 GND I/O signal ground — I/O ground for reference and control.
13 10 V 10 Vdc reference output 10.3 Vdc +/- 3% 10 Vdc reference voltage.
14 24 V 24 Vdc control output 24 Vdc In/Out Control voltage input/output (100 mA max.).
15 STO_com Safe torque common — Safe torque Off common.
16 STO2 Safe torque Off 2 — Safe torque Off 2 input.
17 STO1 Safe torque Off 1 — Safe torque Off 1 input.
18 R1NO Relay 1 normally open Run Changes state when the drive is in the run state.
19 R1CM Relay 1 common
20 R1NC Relay 1 normally closed
21 R2NO Relay 2 normally open Fault Changes state when the drive is in the fault state.
22 R2CM Relay 2 common
Notes:
The above wiring demonstrates a SINK configuration. It is important that CMA is
wired to ground (as shown by dashed line).
If a SOURCE configuration is desired, wire 24 V to CMA and close the inputs to
ground. When using the +10 V for AI1, it is important to wire AI1- to ground (as
shown by dashed line).
 AI1+ support 10 K potentiometer.
