4.5.4 PID Parameters
Code Possible Settings
IMPORTANT
No. Name Default Selection
P200 PID Mode 0 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...P123) 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 (s and t).
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.
