uses this register data for the examples:
•
The bypass for slave 1 is set for Forward run with a frequency reference of 60.00 Hz.
•
The setting in
H5-25

H5-28
and the data in the specified holding registers are as follows.
–
H5-25
= 0044H:
U1-05 [Motor Speed]
= 60.00 Hz (6000 = 1770H)
–
H5-26
= 0045H:
U1-06 [Output Voltage Ref]
= 200.0 V (2000 = 07D0H)
–
H5-27
= 0042H:
U1-03 [Output Current]
= 50% of rated current (100% = 8192, 50% = 4096 = 1000H)
–
H5-28
= 0049H:
U1-10 [Input Terminal Status]
= 00H
If parameter values are changed using the Write command, an Enter command is necessary to activate and save the
