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
When selecting one of analog input current and voltage, make sure that the other
is not inputted.
Terminal name
• Initialization of a voltage signal by an external command
Common terminal for intelligent output terminal
and . The sum of both analog input signals is outputted
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
ON.
H O OI L H O OI L
VRO DC0 to 10 V
(500 to 2 k ) DC0 to 5V
Input impedance 30 k
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)
When each operator is used, and arrival signal can be
outputted at an optional frequency.
The transistor output is turned ON during running.
(Outputted even during DC injection braking)
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.
