NOTE 4
Resetting to 50 and 60 Hz default settings will set the Assertion Level (P120) to “2” (High).
P120 may need to be reset for the digital input devices being used. An F.AL fault may occur

if P120 and the Assertion switch are not set identically.
NOTE 5
If an EPM that contains data from a previous compatible software version is installed:
• The drive will operate according to the previous data, but parameters cannot be changed

(cE will be displayed if attempted)

• To update the EPM to the current software version, set P199 = 5. The parameters can now

be changed but the EPM is incompatible with previous software revisions.

P200

PID Mode

0 Disabled

• Normal-acting: As feedback increases, motor

speed decreases

• Reverse-acting: As feedback increases, motor

speed increases

• PID mode is disabled in Vector Torque mode

(P300 = 5)

• Selections 3, 4: If P112=1, PID controller output

sets the speed, (range -max freq to +max freq)

1 Normal-acting
2 Reverse-acting
3 Normal-acting, Bi-directional
4 Reverse-acting, Bi-directional

NOTE
To activate PID mode, one of the TB-13 inputs (P121...P124) must be used to select the
Auto Reference that matches the desired PID setpoint reference. If the selected PID setpoint
reference uses the same analog signal as the PID feedback (P201), an F.IL fault will occur.

Example: The desired PID setpoint reference is the keypad (p and q). Set TB-13x = 6
(Auto Reference: Keypad):
• TB-13x = closed: PID mode is active
• TB-13x = open: PID mode is disabled and the drive speed will be controlled by the

reference selected in P101.

p201

PID Feedback Source

0 4-20 mA (TB-25)

Must be set to match the PID feedback signal

1 0-10 VDC (TB-5)
2 Drive Load (P507)
3 Feedback from Network
