5. Use outside the rated voltage
The servo drive must not be used outside the allowable voltage range specified in this
manual. Otherwise, components inside the servo drive may be damaged. If required, use
a corresponding voltage step-up or step-down device.
6. Prohibition of changing three-phase input into two-phase input
Do not change three-phase input of the servo drive into two-phase input because this will
cause faults or damage to the servo drive.
7. Surge suppressor
The servo drive has a built-in varistor for suppressing the surge voltage generated when
the inductive loads (electromagnetic contactor, electromagnetic relay, solenoid valve,
electromagnetic coil and electromagnetic brake) around the servo drive are switched on
or off. If the inductive loads generate a very high surge voltage, use a surge suppressor
for the inductive load or use a surge suppressor together with a diode.
Do not connect the surge suppressor on the output side of the servo drive.
8. 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. Contact the agent or Inovance for technical
support.
9. Special usage
If wiring that is not described in this manual such as common DC bus is applied, contact
the agent or Inovance for technical support.
10. Disposal
The electrolytic capacitors on the main circuits and PCB may explode when they are burnt.
Poisonous gas is generated when the plastic parts are burnt. Treat them as ordinary
industrial waste.
