C0.01
-
V/f pattern
• C0.01 can be set to one of the following:
- One of 15 preset patterns (settings 0~14)
- A user-programmable pattern (setting 15)
• C0.01 is not changed by initialization (set B1.01= '1010' or '1111').
However, if C0.01=15, C0.02~C0.08 are changed to the values
associated with the case "C0.01=1" by initialization.
• If C0.01=15, the arbitrary V/f pattern can be generated by properly
setting the values in C0.02~C0.08 as shown in Fig 5.14.
• Normally high starting torque is not necessary except the following
cases:
- Long wiring
- Large voltage drop when started
- AC reactor is connected to the input/output of the
inverter
- Running with a motor smaller than the maximum
applicable motor.
- Needs large starting torque (like as in elevator)
• When using preset V/F patterns, consider the rated voltage &
frequency of the motor and load characteristics as shown in the
following table.
