CFW501 HVAC

Variable Speed Drive

The CFW501 HVAC is a variable speed drive intended for use with asynchronous motors when heating, ventilation, air conditioning and refrigeration applications are to be met. Offering excellent effectiveness, the CFW501 HVAC follows the CFW500 topology with accessories incorporated in the standard version.

The Full HVAC Potential

Fire Mode

This function makes the drive to inhibit its internal faults making the motor run at adverse conditions without stopping the process.

Sleep / Wake-Up Mode

It prevents the operation of the motor at low speeds for certain amount of time to be previously programmed. Also the instant when the motor has to be restar ted can determined by using the wake-up mode.

Broken Belt

It monitors motor torque and prevents it from running with no load in case of a broken belt.

Energy Saving

Depending on the motor speed and load conditions the ﬂux is reduced decreasing losses and therefore efﬁciency is improved causing energy saving.

Filter Maintenance Alarm

It warns about the need to replace the ﬁlter.

Bypass

Using one of its output relay the CFW501 HVAC allows the motor to be started cross the line. An external circuitry is needed for this operation.

Short Cycle Protection

It prevents a compressor/motor from being switched on and off in short period of times.

Dry Pump

It prevents the pump from running with no load.

PTC

Possibility for monitoring PTC se nsor.

Note: 1) Use motor power ratings below only as a guidance. Motors are rated for 400 V, 50 Hz, 4-pole. The right way to size a VFD is matching its output current with

the rated motor current.
