2.7 H: Terminal Functions
Setting 30: PID Integral Reset
By configuring one of the contact inputs for PID integral reset (H1-
PID control will be reset to 0 whenever the input terminal is closed. Refer to
details.
Setting 31: PID Integral Hold
By configuring one of the contact inputs for PID integral hold (H1-
control is held as long as the input terminal is active. The PID controller resumes integral operation from the held value
as soon as the input terminal is released. Refer to
function.
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.
Refer to d1-01 to d1-17: Frequency Reference 1 to 16 and Jog Frequency Reference on page
Setting 33: Thermostatic Switch (N.C.)
Triggers a TME2 alarm when the contact closes, and then thermostatic switches are OFF.
Setting 34: PID Soft Starter Cancel
A contact input configured as a PID soft starter cancel input (H1-
starter and cancel the PID accel/decel time (b5-17). Refer to
Setting 35: PID Input Level Selection
Allows an input terminal to switch the sign of the PID input. Refer to
Setting 40, 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 will operate in reverse. Closing both inputs simultaneously will cause an external fault.
Note: This function cannot be used simultaneously with settings 42 and 43.
Setting 42, 43: Run and Direction Command 2 for 2-Wire Sequence 2
When an input terminal programmed for 42 is closed, the drive will operate in the direction selected. When the input
opens, the drive will stop. The input programmed for 43 selects the direction. If it is closed, the reverse direction is
selected. If it is open, the forward direction is selected.
Note: This function cannot be used simultaneously with settings 40 and 41.
Setting 44, 45, 46: Offset Frequency 1, 2, 3
These inputs add offset frequencies d7-01, d7-02, and d7-03 to the frequency reference. Refer to
Frequency 1 to 3 on page 155
Setting 60: DC Injection Braking Command
When a DC Injection Braking command is input while the drive is stopped, DC Injection Braking operation is activated.
When a Run command or a Jog command is input, DC Injection Braking is released. Refer to
on page 108 for details on setting up the DC Injection Braking function.
The diagram below illustrates how the DC Injection Braking function works.
