TRIAL RUN
•
Verify all parameters before operating the drive. Alteration of parameters may be required
depending on application and load.
•
Always apply voltage and current signals to each terminal that are within levels indicated
within this manual.
OPERATION PRECAUTIONS
•
When the Auto Restart function is enabled, keep clear of driven equipment, as the motor will
restart suddenly after the fault reset.
•
The “STOP / RESET” key on the keypad is active only if the appropriate function setting has
been made. Pushing this button the drive will NOT perform a safe stop. It is available STO
optional board, which installed with a separate EMERGENCY pushbutton, will disconnect
the power and will be unable to generate torque in the motor with high reliability.
•
If a fault is reset with the reference signal still active, the drive will unexpectedly restart. Verify
that it is permissible for this to happen. Otherwise, it may lead to injury to people.
•
Do not modify or alter internal wiring and spare parts without Power Electronics supervision.
•
Before programming or operating the SD700SP Series, initialise all parameters back to
factory default values.
CAPACITORS DEPLETION
If the drive has not been operated for a long time, capacitors lose their charging characteristics
and are depleted. To prevent depletion, once a year run the device under no-load conditions
during 30-60 minutes.
GROUND CONNECTION
•
Ground the drive and adjoining cabinets to ensure a safety operation and to reduce
electromagnetic emission.
•
Connect the input PE terminal only to the dedicated PE terminal of the drive. Do not use the
case or the chassis screw for grounding.
•
Ground the drive chassis through the dedicated and labelled terminals. Use appropriate
conductors to comply with the local regulations. The ground conductor should be connected
first and removed last.
•
Motor ground cable must be connected to the PE output terminal of the drive and not to the
installation’s ground. We recommend that the section of the ground conductor (PE) should
be equal or greater than the active conductor (U, V, W).
•
If the user decides to use shielded motor cable, ensure a correct 360º shield bonding in both
the drive cabinet and the motor terminal box.
