Setting 30: PID Integral Reset
By configuring one of the digital inputs as an Integral Reset Input, (H1- = 30), the value
of the integral component of PID control can be reset to 0 whenever the configured input is
closed. The integral component of PID control will be held at 0 as long as the configured
digital input is held closed. The
PID Block Diagram on page 63 illustrates how the function
works.
Setting 31: PID Integral Hold
By configuring a digital input for Integral Hold (H1-0 = 31), the value of the integral
component of the PID control is locked as long as the input is active. The PID controller
resumes integral operation from the hold value as soon as the integral hold input is released.
The
PID Block Diagram on page 63 illustrates how the function works.
Setting 32: Multi-Step Speed 4
Used to select the Multi-Step Speeds d1-09 to d1-16 in combination with the Multi-Step
Speed inputs 1, 2 and 3. Refer to
d1-01 to d1-17: Frequency Reference 1 to 16 and Jog
Reference on page 95 for details.
Setting 34: PID SFS Cancel
A digital input configured as a PID SFS Cancel input (H1-0 = 34) can be used to enable or
disable the PID soft starter and thereby canceling the accel/decel time b5-17. The
PID Block
Diagram on page 63 illustrates how the function works.
Function 35: PID Input Level Selection
An input programmed for this function can be used to switch the sign of the PID input. The
PID Block Diagram on page 63 illustrates how the function works.
Setting 40/41: Forward Run / Reverse Run Command for 2-Wire Sequence
Sets the drive for 2-wire sequence.
When the input set to 40 is closed, the drive operates in the forward direction. When the
input set for 41 is closed, the drive will operate in reverse. Closing both inputs at the same
time will result in an external fault.
Note: 1. This function can not be used simultaneously with settings 42 and 43.
<2> Determine whether detection for each fault should be enabled only during run or always detected.
