Speed Pot Setpoint Select

(PI Mode Enable/Disable)

- Set PI MODE (Parameter 61) to NORMAL 4-20 mA (02) or REVERSE 4-20 mA (04) depending

on the system.  Refer to section B.1 to determine whether the system is normal or reverse acting.

- Set TB-13A FUNCTION SELECT (Parameter 10) to 0-10 VDC (02).

- Close TB-13A to TB-2 to put the drive into PI mode.  The Speed Pot can then be used to adjust the

PI setpoint.

- Open TB-13A to TB-2 to disable PI mode and control speed directly by the method selected in

STANDARD SPEED SOURCE (Parameter 05).  For example, if Parameter 5 is set to 0-10 VDC, a
speed pot could be used for manual speed control when the PI mode is disabled.  In this case, one
speed pot would serve two purposes:  adjusting the setpoint when PI mode is enabled, and adjusting
the motor speed directly when PI mode is disabled.

NOTE 1:  When TB-13A is closed to TB-2, the drive's display will flash "PIC" to indicate the drive
is in PI Control mode.  When TB-13A is opened, the display will flash "SPd" to indicate the drive is
in Speed Control mode.

NOTE 2:  The setpoint reference and the PI feedback cannot be the same signal.  If the drive is
mistakenly programmed so that the setpoint reference is the same as the feedback reference, the
setpoint reference will default to the 

!

 and 

"

 buttons.
