Supply voltages and power range 1 x V Features and benefits Side-by-side mounting without derating is possible thanks to the compact, book-style design. The maximum text block size is 20 characters. If a read request for a parameters is for more characters than the parameter stores, the response is truncated.
If the read request for a parameter is for fewer characters than the parameter stores, the response is space filled. Since a parameter value can only be transferred as a whole number, a conversion factor must be used to transfer decimals. Please refer to the section Conversion Index. They are stored as 4x registers - 4FFFF. Readable sizes range from 1 register 16 bits up to 10 registers 20 characters. Readable sizes range from 1 register 2 characters up to 10 registers 20 characters.
If an error occurs, please refer to the Exception Codes section. Broadcast is never supported for reads. Query The query messages specifies the staring coil and quantity of coils to be read. Coil addresses start at zero, i. The LSB of the first data byte contains the coil addressed in the query. If the returned coil quantity is not a multiple of eight, the remaining bits in the final data byte will padded with zeros toward the high order and of the byte. The Byte Count field specifies the number of complete bytes of data.
When broadcast the function forces the same coil references in all attached slaves. Query The query message specifies the coil 65 parameter write control to be forced. Query The query message specifies the coils 17 to 32 speed set-point to be forced. Query The query message specifies the starting register and quantity to be read.
Register addresses start at zero, i. For each register, the first byte contains the high order bits and the second contains the low order bits. Query The query message specifies the register reference to be preset.
Query The query message specifies the register references to be preset. Example Write In par. Braking current and duration are set in par. The frozen output frequency can then be changed only by means of the digital inputs par.
Reset is activated on the signal's leading edge, i. The function is only possible when Multi set-ups is selected in par. Bit Not used. Depends on par. The frequency converter is ready for operation, but there is an active coasting command via the digital inputs or via serial communication.
The frequency converter released the motor. The frequency converter can start the motor when a start command is given. It is not possible to control the frequency converter via serial communication. Negative figures are formatted by means of 2's complement.
Feedb [4] Max. Current Inv. Parameter values are transferred as whole numbers only. Conversion factors are therefore used to transfer decimals according to the table below. Example: Par. To set the parameter to 2. The Conversion Factor of 0.
The vale transferred on the bus is thus perceived as 2. Conversion index Conversion factor 2 10 1 0 1 -1 0. Value Terminal 33 High Ref. Value 6. Value Terminal 53 High Ref.
Value Terminal 60 High Ref. LCP potentiometer High Ref. Inverter Thermal Inv. Status Word 6. A wrong password was entered 1 These faults may be caused by mains distortions. Installing Danfoss Line Filter may rectify this problem. Missing phase on supply side, or too high voltage imbalance. Check supply voltage. Intermediate circuit voltage exceeds limit. Thermistor or thermistor connection is disconnected. Torque exceeds value set in either par.
Inverter peak current limit is exceeded. Discharge from output phases to ground. Short-circuit in motor or on motor terminals. No communication to frequency converter. Brake resistor is short-circuited, thus brake function is disconnected. Brake transistor is short-circuited, thus brake function is disconnected. Motor phase U is missing. Check the phase. Motor phase V is missing.
Motor phase W is missing. Contact local Danfoss supplier. Motor current is too low. Check settings. VLT overload. All parameter settings are initialized to default settings. Occurs when copying from LCP if data are moved between frequency converters with major differences in software versions. Occurs when trying to write to a read-only parameter.
LCP and RS connection are trying to update parameters simultaneously. Occurs when trying to write an illegal value to a parameter. Occurs when trying to set a value outside the range. Parameter can only be changed when the motor is stopped. Occurs when using a wrong password for changing a password-protected parameter.
Power loss at rated load conditions. Cable lengths and cross sections: Max. The required action is described in this section.
If the frequency converter is operated at high ambient temperature, the continuous output current should be decreased. Below m altitude no de-rating is necessary but above m the ambient temperature or the maximum output current should be decreased.
A problem may occur at low speeds in constant torque applications. Running continuously at low speeds — below half the nominal motor speed — may require additional air cooling. Alternatively, choose a larger motor one size up. And, thanks to its coated PCBs, the drive ensures reliable and cost-effective operation also in demanding environments.
Lifetime of the drive is extended and reliability improved as a result of the effective heat sink that removes heat from the electronics. Energy consumption can be reduced as kinetic energy in the application can be transformed into braking power to slow down the motor. Get a quote.
