Description

Frequency command power

• Initialization of a voltage signal by an external command

terminal

is between 0 and 10 VDC. (Switching from 0 to 5V is executed

by A48.) When inputting 4 - 20 mA, turn the input terminal at

Frequency command

ON.

common terminal

When a current is inputted from between OI and L and the value is 4 mA,

the output frequency may 0.6 Hz. If this occurs, set a value more than the

frequency which is outputted by [A 4] start frequency setting.

(NOTE 2)

Common terminal 2

Common terminal for intelligent output terminal

Frequency arrival signal

When each operator is used, and arrival signal can be

outputted at an optional frequency.

Signal during run

The transistor output is turned ON during running.

(Outputted even during DC injection braking)

Over-torque signal

The transistor output is turned ON when the torque is more

than the set value.

The set value can be changed by the remote operator.

Use this function only under the sensor less vector control.

NOTE 1: To set four or more multispeeds, use the CF3 terminal.

NOTE 2: When an inconvernience occurs in the above characteristics, adjust it using

and . The sum of both analog input signals is outputted

When selecting one of analog input current and voltage, make sure that the other is not inputted.
