11 Maintenance
Only let authorized persons do maintenance, examine, or replace components on the drive.
Read this manual carefully and know all the precautions and safety information before installing, wiring,
repairing, or examining the drive or replacing components.
Examine and maintain the drive and peripheral devices regularly to extend the life of the drive and decrease
performance deterioration, decrease early wear, and decrease drive failures.
Regular examinations and maintenance will also decrease system downtime.
Refer to the Technical Manual for more information about maintenance and examinations.
Examine the drive one time each year at a minimum.
The operating conditions, environmental conditions, and use conditions will have an effect on the examination
frequency for connected equipment.
Examine the drive more frequently if you use the drive in bad conditions or in these conditions:
• High ambient temperatures
• Frequent starting and stopping
• Changes in the AC power supply or load
• Too much vibration or shock loading
• Dust, metal dust, salt, sulfuric acid, or chlorine atmospheres
• Unsatisfactory storage conditions.
The drive has Maintenance Monitors that keep track of component wear and warn maintenance period when the
estimated performance life is approaching. This Maintenance Monitor eliminates the need to shut down the entire
system for unexpected problems.
Users can set alarm notifications to inform the maintenance periods for a specific drive component.
12 Drive Control, Duty Modes, and Programming
◆ Application Preset
WARNING
Sudden Movement Hazard. Check the I/O signals and the external sequences for the drive before you set the
Application Preset function. When you set the Application Preset function (A1-06 ≠ 0), it changes the I/O terminal functions for
the drive and it can cause equipment to operate unusually. This can cause serious injury or death.
The drive software contains the application presets shown below. Set A1-06 [Application Selection] to align with
the application to let the drive automatically set the best parameter settings for the selected application.
Set application preset as necessary. The device changes the related parameters based on A1-06 as shown in Table
12.1.
Application A1-06 Description
Crane (Hoist) 1
The drive automatically sets the parameters for a hoist application.
Note:
Make sure that you do Auto-Tuning after you set A1-06 for a hoist application.
Crane (Traveling)
2
The drive automatically sets the parameters for a traveling application.
Closed Loop Crane (Hoist) 3
The drive automatically sets the parameters for a closed loop crane (hoist) application.
Note:
After you set A1-06 for a closed loop crane (hoist) application, make sure that you do Auto-Tuning.
Note:
• Before you set A1-06, make sure that you set A1-03 = 2220 [Initialize Parameters = 2-Wire Initialization] to initialize parameters.
• It is not possible to change the A1-06 value. To set an application preset, set A1-03 = 2220 to initialize parameters, then set this
parameter. If initializing all parameters will cause a problem, do not change the settings.
