6. When the external voltage exceeds the rated voltage range
Do not operate the servo drive outside the rated voltage range specied in this User Manual. Failure to comply
may result in damage to the components inside the servo drive. If necessary, use an appropriate voltage step-
up or step-down device to match the supply voltage to the rated voltage range for the servo drive.
7. Prohibition of three-phase input changed into two-phase input
Do not change a three-phase input of the servo drive into a two-phase input. Failure to comply may result in a
fault or damage to the servo drive.
8. Surge suppressor
The servo drive has a built-in voltage-dependent resistor (VDR) for suppressing the surge voltage generated
when the inductive loads around the servo drive (for example the electromagnetic contactor, electromagnetic
relay, solenoid valve, electromagnetic coil and electromagnetic brake) are switched on or off.
If the inductive loads generate a very high surge voltage, use a surge suppressor for the inductive
load and possibly also use a diode.
Note
Do not connect the surge suppressor to the output side of the servo drive.
9. Altitude and de-rating
In places where the altitude is above 1000 m, the cooling effect reduces due to thin air, and it is necessary to
de-rate the servo drive. For details, contact Inovance for advice.
10. Some special usages
If your installation requires special cabling that this user manual does not describe, for example to support a
common DC bus, contact Inovance for technical support and advice.
11. Disposal
If it becomes necessary to dispose of any part of the servo drive system, DO NOT attempt to burn the parts
on a re. If you do, the electrolytic capacitors might explode, and the plastic components will create poisonous
gases. Treat any parts for disposal as ordinary industrial waste.
12. Adaptable motor
•
The standard adaptable motor is a PMSM.
•
The standard parameters of the adaptable motor have already been congured inside the servo drive.
However, it is still necessary to perform motor auto-tuning or to modify the default values based on actual
conditions. Otherwise, the running result and protection performance will be adversely affected.
•
The servo drive might cause an alarm or might be damaged when a short-circuit exists on cables or
inside the motor. Therefore, perform insulation short-circuit test when the motor and cables are newly
installed or during routine maintenance. During the test, disconnect the servo drive from the tested parts.
13. Overcurrent and overload
When an overcurrent fault (Err02, Err03, or Err04) or overload fault (Err10) occurs, if the fault persists after you
power off the servo drive and start it again, nd out the causes rather than starting the servo drive frequently.
Otherwise, the inverter module will be damaged by the large rush-in current.
