Required data

The following data is required to ensure startup is successful:

• Motor type (SEW-EURODRIVE or third-party motor)
• Motor data
• Nominal voltage and nominal frequency.
• Additionally for third-party motors: Nominal current, nominal power, power factor cos φ and nominal speed.
• Nominal line voltage

The following data is also needed for startup with a speed controller:

• Encoder type and encoder resolution:

• Motor data
• SEW‑EURODRIVE motor: Brake yes or no and flywheel fan (Z fan) yes or no.
• Third-party motor: Mass moment of inertia of motor, brake and fan
• Stiffness of the closed-loop control system (factory setting = 1; suitable for most applications)

If the drive tends to oscillate → setting < 1

Transient recovery time is too long → Setting > 1

Recommended setting range: 0.80 – 1 – 1.10 (factory setting = 1)

• Converted mass moment of inertia of the load (gear unit + driven machine) on the motor shaft.
• Time required for the shortest ramp

INFORMATION

• Activate encoder monitoring (P504 = "ON") after completing the startup. The function and voltage supply of the encoder will then be monitored.
• If a Hiperface^® encoder is connected, it is always monitored regardless of the setting of parameter P504. Encoder monitoring is not a safety function!
