B8. Reinstall and secure drive cover.
B9. Place this instruction sheet with the drive technical manual.
THIS COMPLETES INSTALLATION OF THIS OPTION IN THE VCD 703.
(2) Reference Inputs: The AI-14B can be programmed for either speed mode references or torque
mode references by programming Sn-25; see Table B4.
(3) Monitor Display: Inputs to the AI-14B can be monitored by the VCD 703 by using the Un-XX
constants.
Un-36 = CH1 input voltage (V) 10V / 10V
Un-37 = CH2 input voltage (V) 10V / 10V
Un-38 = CH3 input voltage (V) 10V / 10V
