<2> Determine whether detection for each fault should be enabled only during run or always detected.
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.
Refer to PID Block Diagram on page 117
for details.
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.
Refer to PID Block Diagram on page 117
for details.
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 135
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.
Refer to PID Block Diagram on page 117
for details.
Function 35: PID Input Level Selection
An input programmed for this function can be used to switch the sign of the PID input.
Refer to PID Block Diagram on
page 117
for more information on this function.
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.
These functions are assigned to the terminals S1 and S2 when the drive is initialized for 2-Wire sequence.
