MCH41A0150-503-4-00 - Inverter drive - SEW

MOVIDRIVE® compact is the term used to describe the compact and powerful inverters from SEW-EURODRIVE. Perfectly suited to your needs, you can use MOVIDRIVE® compact to implement frequency converters in the power range from 1.5 to 90 kW. Thanks to proven inverter technology and SEW control modes, you can meet the highest demands in terms of dynamics and control quality.

The MOVIDRIVE® compact product line comprises four series:

• MOVIDRIVE® compact MCF: drive for three-phase asynchronous motors without encoder feedback, VFC control mode.

• MOVIDRIVE® compact MCV: Inverter for three-phase asynchronous motors with feedback encoder, VFC or CFC control mode.

• MOVIDRIVE® compact MCS: Inverter for synchronous servomotors with encoder (resolver), SERVO control mode.

• MOVIDRIVE® compact MCH: Inverter for three-phase asynchronous motors, asynchronous servomotors or synchronous servomotors. Feedback encoder with either a Hiperface encoder, sin/cos encoder or TTL sensor.

The MCF, MCV and MCS series are available in 2 variants:

• MCF/MCV/MCS40A: Control via binary inputs and setpoint selection via analog setpoint input.

• MCF/MCV/MCS41A: control via PROFIBUS-DP interface or binary inputs. Setpoint selection via PROFIBUS-DP interface.

The MCH series is available in 3 variants:

• MCH40A: Control via binary inputs and setpoint selection via analog setpoint input.

• MCH41A: Control via PROFIBUS-DP interface, binary inputs or analog outputs. Setpoint selection via PROFIBUS-DP interface.

• MCH42A: Control via INTERBUS-LWL interface (FO) or binary inputs. Setpoint selection via the INTERBUS-LWL (FO) interface.

MOVIDRIVE® compact inverters are available in two versions: the standard version and the application version.

The devices are equipped with the integrated positioning and sequence control system IPOSplus® as standard and can be expanded with available options.

The standard version is indicated by the characters "00" at the end of the unit designation.

In addition to the features of the standard version, these units include "electronic cam" and "internal synchronism" function technology. You can also use all application modules available in the MOVITOOLS® software package with the application versions.

The application version is indicated by the characters "0T" at the end of the unit designation.

Unit properties

• Wide voltage range

– AC 400/500 V devices for the voltage range 3 × AC 380 ... 500 V

– AC 230 V devices for the voltage range 3 × AC 200 ... 240 V

• High overload capacity

– 150% IN, short term

– 125% IN, continuous operation without overload (pumps, fans)

• With a switching frequency of 4 kHz, IN is permitted for an ambient temperature ϑ = 50 °C

• 4Q capability thanks to integrated brake chopper fitted as standard

• Compact unit design for minimal control cabinet footprint and control cabinet volume utilization

• Integral line filter fitted as standard in frame sizes 1 and 2, compliant with Class A limit on input side without any additional measures

• 6 isolated binary inputs and 3 binary outputs including a relay output, programmable inputs/outputs

• 1 TF/TH input for motor protection via PTC thermistor or thermocontact

• 3-color LEDs for displaying operating and error states

• Separate DC 24 V voltage input for supplying the inverter electronics (parameterization, diagnostics and data backup even when the power system is switched off)

• Pluggable connection unit and, for MOVIDRIVE® compact MCH4_A, separable electronic terminals

• Separable power terminals for size 1 units

Control functionality

• VFC or CFC control modes for field oriented operation (asynchronous servo)

• With MCH4_A: three-phase asynchronous or synchronous motors can be operated

• IPOSplus® positioning and sequential control system integrated as standard

• 2 full parameter sets

• Automatic motor calibration

• Automatic brake control by the drive

• DC braking to decelerate the motor even in 1Q mode

• Slip compensation for high static speed accuracy even without encoder feedback

• Flying restart circuit to synchronize the inverter to an already spinning motor

• Lifting capacity with all motor systems that can be connected

• Protection against motor pull-out thanks to sliding current limitation in the field weakening range

• Function to hide the speed window to avoid mechanical resonances

• Heating current to avoid a
