B.5 DESCRIPTION OF PI PARAMETERS
P10 TB-13A FUNCTION SELECT
12 KEYPAD SETPOINT: This option has been added so that the and buttons on the
front of the drive can be used as the PI setpoint reference source. Closing TB-13A to
TB-2 will enable the PI mode and the and buttons can be used to select the desired
process setpoint.
P11 TB-13B FUNCTION SELECT
09 KEYPAD SETPOINT: This option has been added so that the and buttons on the
front of the drive can be used as the PI setpoint reference source. Closing TB-13B to
TB-2 will enable the PI mode and the and buttons can be used to select the desired
process setpoint.
P12 TB-13C FUNCTION SELECT
10 KEYPAD SETPOINT: This option has been added so that the and buttons on the
front of the drive can be used as the PI setpoint reference source. Closing TB-13C to
TB-2 will enable the PI mode and the and buttons can be used to select the desired
process setpoint.
P61 PI MODE
This parameter must be set to match the type of system and the type of feedback signal
used. A direct acting system is one that requires the motor speed to increase as the feedback
signal decreases, while a reverse acting system requires the motor speed to decrease as the
feedback signal decreases.
01 DISABLED Disables the PI function to allow standard drive operation.
02 NORMAL 4-20 mA Enables the PI function for a direct-acting system with a 4-20
mA feedback signal.
03 NORMAL 0-10 VDC Enables the PI function for a direct-acting system with a 0-10
VDC feedback signal.
04 REVERSE 4-20 mA Enables the PI function for a reverse-acting system with a 4-20
mA feedback signal.
05 REVERSE 0-10 VDC Enables the PI function for a reverse-acting system with a 0-10
VDC feedback signal.
When PI is disabled, the drive will operate in an OPEN LOOP mode, responding directly to
a speed reference source selected using STANDARD SPEED SOURCE (Parameter 05) or
terminals TB-13A, 13B, and/or 13C).
P62 MIN FEEDBACK
This parameter should be set to the value of the process variable that corresponds to the
minimum transducer feedback signal (0 VDC or 4 mA). See the example below.
P63 MAX FEEDBACK
This parameter should be set to the value of the process variable that corresponds to the
maximum transducer feedback signal (10 VDC or 20 mA). See the example below.
