E5 Series High Performance Universal Inverter
P7.T8
This parameter is used to detect the load. If the output terminal is set to "TT: Zero current detection
arrival", the output will be active if the output current is lower than the zero current detection level P7.T8.
Note:
 This function parameter is percentage of rated current of the motor.
P7.T9
This parameter is used to detect the deviation between output frequency and reference frequency.
Once on of the output terminal function is set to "T: Running frequency arrival output", the deviation
between the output frequency and the reference frequency of is in the range of P7.T9 setting, the output
will be active, as shown in the figure. Yi represents YT T YT terminals or relay terminal.
P7.T0
P7.TT
P7.TT
P7.T3
These parameters are used for detecting whether the output frequency in within the setting range. If one
of the output terminal function is set to "T: Frequency level detection T output" or "3: Frequency level
detection T output", the terminal output will be enabled if the output frequency is in the FDT range.
