Extra inputs/outputs can be added by installing an optional I/O extension module
(CMOD-01, CMOD-02 or CHDI-01) in drive slot.
Local control
The control commands are given from the control panel keypad or from a PC
equipped with Drive composer when the drive is in local control. Speed and torque
control modes are available in vector motor control mode; frequency mode is
available when scalar motor control mode is used (see parameter
mode).
Local control is mainly used during commissioning and maintenance. The control
panel always overrides the external control signal sources when used in local control.
Changing the control location to local can be prevented by parameter
control
disable.
The user can select by a parameter
reacts to a control panel or PC tool communication break. (The parameter has no
effect in external control.)
External control
When the drive is in external (remote) control, control commands are given through
• the I/O terminals (digital and analog inputs), or optional I/O extension modules
• the fieldbus interface (via the embedded fieldbus interface or an optional fieldbus
adapter module).
