■ Different Methods of Drive initialization
1110: Resets all parameters to user-defined default values
A “user-initialization” resets all parameters to a user-defined set of default values
previously saved to the drive. Set parameter o2-03 to 2 to clear the user-defined
default values.
Note: Set o2-03 to 1 to save the current parameter settings and changes for a “user-
initialization.” After all parameter setting changes have been saved, parameter o2-03
automatically returns to 0. Refer to Verifying Parameter Settings and Backing Up
Changes on page 172.
2220: 2-Wire Initialization
Returns all parameters to factory default values for 2-wire control.
3330: 3-Wire Initialization
Returns all parameters to factory default values for 3-wire control.
Note: Refer to Run Command Input Selection: b1-02 on page 133, for more information
on a 2-wire and 3-wire sequence.
1110: User Initialization
Returns all parameters to backed-up values stored at the time the user set o2-03 = 1
and pressed enter to back-up parameter settings.
5550: Reset of OPE4 fault condition
Resets an OPE4 fault condition caused by a parameter setting conflict. Parameter
setting values may be lost.
◆ Drive Duty Mode and Carrier Frequency Selection
■ C6-01: Drive Duty Mode Selection
The drive has two different duty modes which must be selected based on the load
characteristics. The drives rated current, overload capability and the stall
prevention levels during acceleration will change depending on the duty mode
selection. Heavy Duty allows over load up to 150% for 1 min, Normal Duty allows
up to 120% for 1 min. but therefore the drives rated current is higher. Refer to
Specifications on page 313 for details about the rated current.
