Shielding clip is used for grounding the shielding layer of motor and braking resistor cables to ensure high frequency and low impedance.
For sizes 4-7, touch protection covers (such as DLB11B, DLB21B) need to be installed to achieve IP20 protection level.
4.2 EMC compliant installation (EN 61800-3)
Shielded cables: All signal cables must be shielded and grounded extensively at both ends. The motor cable can be shielded or an HD output choke can be used.
Line filter (NF series): used to meet C1 or C2 class limits, installed near the frequency converter, with a connection length of ≤ 400 mm.
Output choke (HD series): Only the U, V, and W phases pass through the magnetic core, and the PE line does not pass through. HD001- HD003 are suitable for different cable cross-sections.
Output filter (HF series): Sine filter, only used for VFC and V/f modes, not for elevator applications. Pay attention to voltage drop and PWM frequency limitation when using (12/16 kHz requires connection to DC bus terminal V5).
4.3 IT Systems
MOVIDRIVE ® B is allowed to run on IT systems (ungrounded star points), but EMC limits do not apply. It is recommended to use an insulation monitoring instrument with pulse coding measurement to avoid false tripping caused by the grounding capacitance of the frequency converter.

6.2 Quick Start Process (Taking DBG60B as an Example)
Ensure that X13:1 (DI00 "/Controller inhibit") is a "0" signal.
Enter the context menu and select 'STARTUP'.
Select the parameter set (1 or 2) and choose the motor type (SEW or third-party).
Enter the motor nameplate data (rated voltage, frequency, current, power, cos φ, speed).
If using an encoder, select the encoder type and resolution.
Set closed-loop stiffness (default 1.0), input load inertia and minimum ramp time.
Perform calculations and save parameters.
After startup, it is recommended to activate the encoder monitoring (P504=ON).
