Setting 30: PID Integral Reset
Configuring one of the digital inputs for PID integral reset (H1-oo = 30) resets the value of the integral component in PID
control to 0 when the terminal is closed.
Setting 31: PID Integral Hold
Configuring a digital input for Integral Hold (H1-0o = 31) locks the value of the integral component of the PID control 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.
Setting 32: Multi-Step Speed Reference 4
Selects the multi-step speeds d1-09 to d1-16 in combination with the input terminal set for Multi-Step Speed 1, 2 and 3.
Setting 34: PID Soft Starter Cancel
A digital input configured as a PID soft starter cancel input (H1-0o = 34) enables or disables the PID soft starter and cancels
the PID accel/decel time (b5-17).
Setting 35: PID Input Level Selection
Allows an input terminal to switch the sign of the PID input.
Settings 40 and 41: Forward Run, Reverse Run Command for 2-Wire Sequence
Configures the drive for a 2-Wire sequence.
When an input terminal set to 40 closes, the drive operates in the forward direction. When an input set for 41 closes, the drive
operates in reverse. Closing both inputs simultaneously will result in an external fault.
Note: 1. This function cannot be used simultaneously with settings 42 and 43.
2. The same functions are assigned to terminals S1 and S2 when the drive is initialized for 2-Wire sequence.

Settings 42 and 43: Run and Direction Command for 2-Wire Sequence 2
Sets the drive for 2-Wire sequence 2.
When an input terminal programmed for 42 closes, the drive will operate in the selected direction. The drive will stop when
the input opens.
The input programmed for 43 selects the direction. If the input is open, forward direction is selected. If the input is closed,
reverse direction is selected.
Note: This function cannot be used simultaneously with settings 40 and 41.
Setting 47: Node Setup
If the SI-S3 option card is connected, closing this terminal sets a node address for operation on a CANopen network.
Setting 60: DC Injection Braking Command
DC Injection Braking is activated when a DC Injection Braking command is input while the drive is stopped. DC Injection
Braking is released when a Run command or a Jog command is input.
The diagram below illustrates DC Injection Braking:
