PRODUCT DESCRIPTION

When setting the relay characteristic/torque angle for the three phase directional overcurrent element, a positive angle setting was specified. This was due to the fact that we consider as polarising voltage, the phase voltage value in quadrature of the current under fault conditions. With directional earth fault protection, the residual current under fault conditions lies at an angle lagging the polarising residual earth fault voltage.

Description:

The R1 status relay is energized when the drive power is applied with no fault detected. It de-energizes in the event of a detected fault or

when the drive power is removed.

The drive is reset after a detected fault:

• by switching off the drive until the display disappears completely, then switching on again

• automatically in the cases described in the "automatic restart" function, FLt- menu, Automatic restart Atr page 91 set to YES

• via a logic input when this input is assigned to the "drive reset" function, FLt- menu, Detected fault reset assignment rSF page 

91 set to LpH.

Drive thermal detection

Thermal detection is provided by a built-in PTC probe in the power module.

Drive ventilation

Ratings up to 0.75 kW (1 HP) do not include a fan. The fan runs only when the drive thermal state requires ventilation.

Motor thermal detection

Function:

Thermal detection by calculating the I2t.

Note: The motor thermal state memory returns to zero when the drive power is cycled if Motor thermal state memo MtM page 94

is not set to YES.

NOTICE

RISK OF DAMAGE TO THE MOTOR

The use of external overload protection is required under the following conditions:

• Repowering up the product since there is no motor thermal state memory.

• Running multiple motors

• Running motors rated at less than 20% of the nominal drive current

• Using motor switching

Failure to follow these instructions can result in equipment damage.

NOTICE

MOTOR OVERHEATING

• This drive does not provide direct thermal protection for the motor.

• Use of a thermal sensor in the motor may be required for protection at all speeds or loading conditions.

• Consult the motor manufacturer for the thermal capability of the motor when operated over the desired speed range

Failure to follow these instructions can result in equipment damage.
