EM630 Specialized inverter for hoist

EM330D

Open loop inverter for hoist

EM630 mainly used in Tower crane and bridge crane, Close loop control hoisting

equipments

Zero servo function can prevent hook gliding when the brake fails

EM630

Close loop inverter for hoist

Slide4

EM630 Specialized inverter for hoist

Main features

Closed loop vector control, provide over speed protection;

Big torque at low frequency;

Zero servo: Safely release in case of brake failure;

Brake control logic- Brake releases after current and time is up, more safe;

Expandability: Support multiple encoders and I/O.

Slide15

Tower crane after driving by EM630

EM630

Larger tolerance of the input voltage,

The inverter works with mains supply 380V

±

20%

5

System cost: Almost the same.

the cost freed from motor and contactor is similar to the sum of inverter, encoder and brake resistors

Smaller starting current, less influence to other

equipments

in the same power grid.

Life of brake is getting longer and maintenance cost is lower

Safety improves, the zero servo offers further safety protection, No hook gliding

EM630 -Specification

Model

EM630-022-3 ~ EM630-045-3

It refers to EM630 specialized inverter for hoist, 22~45kW,

380V

±

20%

EM630-022-3B ~ EM630-045-3B

Same as above but there is built-in braking choke

Capacity selection

For tower crane, overload may occur during instantaneous starting, quick acceleration and deceleration, in this case, the inverter should be 1~2

power

bigger.
