0 0.01 Hz units
1 0.01% units (The maximum frequency is 100%.)
2 to 39
r/min units (Set the number of poles.)
r/min = 120 X frequency reference (Hz)/o1--03
(o1--03 sets the motor poles.)
40 to 39999
Decimal point is set according to the 5th digit value of o1--03.
5th digit = 0: Displays
5th digit = 1: Displays
.
5th digit = 2: Displays .
5th digit = 3: Displays .
Setting values of 100% frequency are set according to the first to fourth digits of o1--03
[Example 1]
When the setting value (100% speed) is 200.0, o1--03 is set to 12000.
When o1--03 is set to 12000, 100% speed displays 200.0. 60% speed displays 120.0.
[Example 2]
When the setting value (100% speed) is 65.00, o1--03 is set to 26500.
When o1--03 is set to 26500, 60% speed displays 39.00.
