It fits in any control cabinet and starts running straight away - the MOVITRAC LTP-B frequency inverter in IP20. Compact design and simplified handling give you a versatile range of possible applications and make startup quick. Connect, choose your motor, perform the automatic calibration and your application will just run and run. Designed and developed for open-loop speed control of synchronous and asynchronous motors, the MOVITRAC LTP-B with IP20 housing is available with up to 15 kW of power.
MOVITRAC LTP B
Frequency inverters of the MOVITRAC LTP-B series are optimally matched to meet the requirements of applications outside a control cabinet.
They have been designed and developed for controlling the speed of asynchronous & synchronous motors without encoder and are particularly economical in conveyor applications, hoists, as well as in fans and pumps.
For applications in dirty or humid environments, MOVITRAC LTP-B up to a power range of 11 kW is also available as control cabinet housing in IP20 degree of protection.

MOVITRAC LTP-B is available in 2 housing variants:
- Standard IP20 housing for use in switch cabinets
- IP55/NEMA 12k
The IP55 / NEMA 12 k housing is protected against moisture and dust. Therefore, the drives can be operated indoors under harsh conditions. Electronically, the drives are identical and the only differences are the dimensions of the housing and the weight.
Each MOVITRAC LTP-B has an integrated keypad as standard, allowing drive operation and setup without any additional equipment. MOVITRAC LTP-B units have a built-in braking resistor which can be used with an external braking resistor to convert re-generated energy from the motor into thermal energy. This braking circuit is generally needed for applications with a fast deceleration ramp or with a high inertia load.
SEW-EURODRIVE also recommends protecting wire and grid resistors against overload using a bimetallic relay. The relay output must disconnect the supply voltage to the MOVITRAC LTP-B unit. It must not interrupt the connection from the braking resistor to the MOVITRAC LTP-B unit. With the braking resistors BW LT 100 002, SEW-EURODRIVE flat-type braking resistors and any other overload protected braking resistors, the bimetallic relay is not required.
Line chokes reduce supply harmonic distortion and protect MOVITRAC LTP-B units against harmful supply disturbances. They are also used to reduce the effects of the MOVITRAC LTP-B upon supply harmonic distortion. Line chokes are also used to protect the power input circuits of the MOVITRAC LTP-B against voltage spikes which might originate from lightning strikes or other equipment on the same supply.
Output chokes improve the quality of the output waveform. Therefore the maximum cable length stated in the rating table can be doubled when using an output choke. MOVITRAC LTP-B units, like the majority of other inverter drives, have unfiltered outputs. In the majority of applications this will give satisfactory performance, however, in a small number of applications output filtering is strongly recommended to improve system functionality, reliability and longevity.
The basic variant of the MOVITRAC LTP-B has an integrated keypad. For some applications, however, it is necessary to have an additional keypad in a remote area. The keypad option comes with a self adhesive seal and a 3 m long cable to be plugged into the RJ45 connector on the MOVITRAC LTP-B unit. The maximum cable length between the keypad and the drive is 25 m for unshielded cables and 100 m for shielded cables.
As part of the Smart Servo Package, SEW-EURODRIVE offers the new MOVITRAC LTX servo inverter for universal use. It stands out with advantages such as ease of operation, short startup times as well as optimized costs in view of the field of application. The new universal servo inverter is based on MOVITRAC LTP-B, which is additionally equipped with an LTX servo module - therefore the name MOVITRAC LTX. MOVITRAC LTX servo inverters are available in two sizes and cover a power range from 750 to 5500 W. They are particularly suitable for use in applications such as secondary packaging, handling, and logistics.
The Smart Servo Package contains all the components required for a complete automation solution in one coordinated product package. It was optimized specifically for the most important application requirements in the power range up to 5.5 kW and in the voltage range of 1 and 3 x AC 230 V. Using this package, servo and automation tasks can be implemented easier, quicker and more efficiently. Various user and customer interfaces were optimized and simplified for this purpose. The Smart Servo Package offers finely graduated and predefined automation options. SEW-EURODRIVE offers complete solutions with MOVI-PLC (with the software packages CCU, Multimotion and Multimotion light), servomotors, cables, accessories, planetary and right-angle servo gear units (in preparation).
The functionality of the digital inputs within the MOVITRAC LTP is user programmable. The IP55 / NEMA 12 housing is protected against moisture and dust. Therefore, the drives can be operated indoors under harsh conditions. MOVITRAC LTP units have a built in braking transistor which can be used with an external braking resistor to convert re-generated energy from the motor into thermal energy.
This braking circuit is generally needed for applications with a fast deceleration ramp or with a high inertia load. Line chokes are also used to protect the power input circuits of the MOVITRAC LTP against voltage spikes which might originate from lightening strikes or other equipment on the same supply.
