SD315O 11.2 11 Extract Extract for commissioning 11.2.1 Setting the nominal current NOTE: Setting a nominal current higher than the nominal current of the motor may damage or destroy the motor. Parameter switch S1 allows you to set the nominal current. 왘 Set the nominal current of the motor by means of parameter switch S1. NOTE: If the nominal current of the motor is >7.5 A, you must set a value of ≤67 % for the current reduction. Switch setting S1 Nominal current of motor [A] 3 1 [A] 3.
11 Extract SD315O 11.2.2 Setting the current reduction If the full holding torque is not required at standstill, the "Current Reduction" function can be used to reduce the holding torque. @ WARNING FALLING LOAD AT STANDSTILL If the current reduction is enabled, the motor torque at standstill is reduced; if external forces act on the drive (vertical axes), this may cause the load to fall. • Verify that the load conditions allow for operation with current reduction.
SD315O 11 Extract 11.2.3 Setting the Softstep function Parameter switch S2.4 allows you to set the "Softstep" function. If the function is active, the signals at the P/D signals are internally smoothed. This results in smoother motor movements. This results in a temporary position deviation during a motor movement. The magnitude of the position deviation depends on the velocity. The position deviation increases in line with the velocity and may amount to as much as one motor revolution.
11 Extract SD315O 11.2.4 Setting the number of steps The resolution of the drive can be adjusted via the number of steps per revolution. 왘 Switch off all supply voltages. Verify that no voltages are present (safety instructions). 왘 Use parameter switches S3.1 to S3.3 to set the number of steps.

SD315O 11 Extract 11.2.5 Setting the type of Enable Parameter switch S3.4 allows you to set the type of Enable. See chapter 6.2 "Enabling motor movements" for a description of the function. 왘 Switch off all supply voltages. Verify that no voltages are present (safety instructions). 왘 Use parameter switch S3.4 to set the function to "ENABLE" or "GATE". Switch setting S3.
