12) Surge suppressor
The AC drive has a built-in voltage dependent resistor (VDR) for suppressing the surge
voltage generated when the inductive loads (electromagnetic contactor, electromagnetic
relay, solenoid valve, electromagnetic coil and electromagnetic brake) around the AC
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 also use a diode.
Do not connect the surge suppressor on the output side of the AC.
13) Altitude and de-rating
In places where the altitude is above 1000 m and the cooling effect reduces due to thin
air, it is necessary to de-rate the AC drive. Contact Inovance for technical support.
14) Some special usages
If wiring that is not described in this manual such as common DC bus is applied,
contact the agent or Inovance for technical support.
15) 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.
16) Adaptable Motor
• The standard adaptable motor is adaptable four-pole squirrel-cage asynchronous
induction motor or PMSM.
according to the rated motor current.
• The cooling fan and rotor shaft of non-variable-frequency motor are coaxial, which
results in reduced cooling effect when the rotational speed declines. If variable
speed is required, add a more powerful fan or replace it with variable-frequency
motor in applications where the motor overheats easily.
• The standard parameters of the adaptable motor have been configured inside the
AC drive. It is still necessary to perform motor auto-tuning or modify the default
values based on actual conditions. Otherwise, the running result and protection
performance will be affected.
• The AC drive may alarm or even be damaged when 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,
make sure that the AC drive is disconnected from the tested parts.
