Function: Acc/Dec RampHold
Setting: A
The Acc/Dec RampHold function will clamp ("hold") the speed of the output frequency whenever a digital input that has been
programmed for it (H1-0x= A) is closed. All acceleration or deceleration will stop and the Drive will hold the current speed.
Once the input is opened, acceleration or deceleration continues.
The Acc/Dec RampHold function is affected by parameter d4-01. If d4-01= "1: Enabled" and the Acc/Dec RampHold
functions are both being used, whenever the RampHold input is closed the output frequency is memorized. When interrupted
power is returned and a Run command is input, the Speed Command will be the last output frequency memorized by the Acc/
DecRampHold function, if the Acc/Dec RampHold input is still closed.

Function: Term A2 Enable
Setting: C
Any digital input configured as Term A2 Enable (H1-0x= C) when open will cause the input to analog input A2 to be ignored.
If analog input A2 is configured as the Main Reference (H3-13= "1: Main Fref TA1"), then the Term A2 Enable input will have
no effect.
Function: Term Not Used
Setting: F
Any digital input programmed as Term Not Used (H1-0x= F) will have no function assigned to it and it's OPEN/CLOSED state
will not matter to the Drive's operation.
