Example 1: Sequence & Reference From The Digital Operator
- iii -
When the drive is set up with the sequence and the reference coming from the digital operator, it is in “Local”
control. Local control is often used during startup to verify motor operation, rotation, etc. The drive can be
temporarily placed in “Local” control simply by using the LO/RE quick start LED. If power is removed and then
restored, the drive will come up in the “Remote” mode.
The drive can be programmed so that even if power is lost, the drive will come up in the local mode (see Table
2 below).
OPERATION:
•
The frequency reference comes from the digital operator pot.
•
The drive can be started by pressing the
RUN
key on the digital operator.
•
The drive can be stopped by pressing the
STOP
key on the digital operator.
•
The direction of the motor can be changed regardless of motor speed by using F/R quick start LED.
