Master Frequency Command Source (AUTO, REMOTE)
1: RS-485 communication input
2: External analog input (Refer to Pr.03-00)
3: External UP / DOWN terminal (multi-function input terminals)
4: Pulse input without direction command
(Refer to Pr.10-16 without considering direction)
6: CANopen communication card
7: Digital keypad potentiometer knob
8: Communication card (does not include CANopen card)
NOTE:
HOA (Hand-Off-Auto) function is valid only when you use with MO function
setting 42 and 56 or with KPC-CC01 (optional).
Determines the master frequency source in the “AUTO, REMOTE “mode. The default is AUTO
mode.
You can switch the AUTO, REMOTE mode with the keypad KPC-CC01 (optional) or the multi-
function input terminal (MI) to set the master frequency source.
It returns to AUTO or REMOTE mode whenever you cycle the power. If you use a multi-function
input terminal to switch between HAND (LOCAL) and AUTO (REMOTE) mode, the highest
priority is the multi-function input terminal.
The pulse of Pr.00-20 = 4 (Pulse input without direction command) is input by MI7.
When Pr.00-20 = 9, Pr.08-65 automatically set as 1 at the same time. Pr.08-65 needs to be set
as 0 for changing back to other values.
When Pr.00-20 = 7, set Pr.03-40 = 50% and Pr.03-41 (VR Positive / Negative Bias) = 4 (Bias
serves as the center). If you need to reverse the setting, set Pr.03-10 = 1.
Operation Command Source (AUTO, REMOTE)
2: RS-485 communication input
3: CANopen communication card
5: Communication card (does not include CANopen card)
NOTE:
HOA (Hand-Off-Auto) function is valid only when you use with MO function
setting 42 and 56 or with KPC-CC01 (optional).
Determines the operation frequency source in the “AUTO, REMOTE” mode.
In the HOA mode, if the multi-function input terminal (MI) function setting 41 and 42 are OFF, the
drive does not receive any operation command and JOG is invalid.
