Multi-function Digital Inputs (H1-01 to H1-05)
Set Value
Setting Precautions
An OPE03 alarm will occur if one of the following settings are programmed:
Only either the UP command or DOWN command has been set.
•
• UP/DOWN commands and Acceleration/Deceleration Ramp Hold have been programmed to digital inputs
at the same time.
Application Precautions
• When the frequency reference is input by UP/DOWN commands the frequency is limited by the parame-
ters d2-01 to d2-03 (Reference Limits, set in% of the maximum output frequency).
When the frequency reference is input by UP/DOWN commands the analog input A1 becomes the fre-
•
quency reference lower limit. If a combination of the frequency reference from terminal A1 and the fre-
quency reference lower limit is set in either parameter d2-02 or d2-03, the larger limit value will become
the frequency reference lower limit.
If a frequency reference lower limit is set and the RUN command is activated the drive accelerates to the
•
lower limit.
Multi-step operation is disabled when UP/DOWN commands are used.
•
• When d4-01 (Frequency Reference Hold Function Selection) is set to 1, the last frequency reference value
is stored even after the power supply is turned OFF. When the power supply is turned ON and the run com-
mand is input, the motor accelerates to the frequency reference that has been stored. To reset (i.e., to 0 Hz)
the stored frequency reference, turn ON the UP or DOWN command before the power is switched on.
