CONTROL FUNCTIONS (CONT’D)

Constant speed by the auto deceleration mode can be temporarily released by acceleration use even the operation oil pressure switch is: APP-IP4=OFF, as shown in [Figure 10-40-38]. The operated accelerator’s target speed is followed during the deceleration release (optional).

Application Interface Outline (Cont’d)

High idling limitation feature

When the high idling limitation control is enabled, the Eco-governor has a feature which temporarily reduces the high idling speed by the external switch input (APP-IP5).

Like [Figure 10-40-39], the maximum target speed can be limited by the accelerator input voltage by connecting the high idling limitation switch to the APP-IP5 terminal. The switch used can be selected from the following 2types: normal open type and normal close type.By default, normal open type is set, so the maximum speed is limited when the APPIP5 terminal is GND connected.

The speed for high idling limitation can be switched by the condition of high idling limitation speed switch, or droop or isochroous drives.Also, the settings of the limitation speed can be changed. (The default settings can be switched by the high idling limitation speed switch condition of 1900min-1 or 1700min-1).

The speed of limitation is the target speed at no load.The actual maximum speed is decided by the size of load.
