5.7 H: Terminal Functions
YASKAWA ELECTRIC SIEP C710616 30B YASKAWA AC Drive T1000A Technical Manual 187
Parameter Details
5
Setting 1B: Program lockout
When an input is programmed for Program Lockout, parameters values cannot be changed as long as this input is open (it
is still possible to view and monitor parameter settings).
Setting 20 to 2F: External fault
By using the External fault command, the drive can be stopped when problems occur with external devices.
To use the External fault command, set one of the multi-function digital inputs to any value between 20 to 2F. The digital
operator will display EF where is the number of the terminal to which the external fault signal is assigned.
For example, if an external fault signal is input to terminal S3, “EF3” will be displayed.
Select the value to be set in H1- from a combination of any of the following three conditions:
• Signal input level from peripheral devices (N.O., N.C.)
• External fault detection method
• Operation after external fault detection
The following table shows the relationship between the conditions and the value set to H1-:
Setting 30: PID integral reset
By configuring one of the digital inputs for PID integral reset (H1- = 30), the value of the integral component in PID
control will be reset to 0 whenever the terminal is closed. Refer to PID Block Diagram on page 129 for more 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 129 for more information on this function.
Setting 34: PID soft starter cancel
A digital input configured as a PID soft starter cancel input (H1-0 = 34) can be used to enable or disable the PID soft
starter and thereby canceling the PID accel/decel time (b5-17). Refer to PID Block Diagram on page 129.
Setting 35: PID input level selection
Allows and input terminal to switch the sign of the PID input. Refer to PID Block Diagram on page 129 for details.
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 at the same time will result in an external fault.
Setting
<1> Determine the terminal status for each fault, i.e., whether the terminal is normally open or normally closed.
<2> Determine whether detection for each fault should be enabled only during run or always detected.
