KOLLMORGEN 6SM47L-3.000-G motor current and voltage

Description

The 6SM47L-3.000-G inductive phase shift between the motor current and the motor voltage can be compensated at high speeds. With the given voltage conditions, a higher torque can be achieved at the speed limit. Alternatively, the achievable speed limit can be increased by up to 30%. The phase shift is increased (depending on the motor speed) linearly from the Start Phi value up to the final value = Limit Phi. The optimum setting depends on the motor type and the speed limit.

The servo amplifier uses setpoint input 1 as the current (torque) or speed setpoint, depending on the setting of OPMODE. Setpoint input 2 is used for the input from a Ferraris sensor (acceleration sensor) to implement speed control in conjunction with the feedback system.

Determines the feedback source for the internal position controller. For most applications, the position information for commutation and for position control are derived from the same source. This source is determined on the “FEEDBACK” screen page, and can be either a resolver or an Endat/Hiperface encoder. In certain situations it may be advisable to derive the position information for commutation from a different source to that for the position control. In such a case the feedback parameter will continue to be the source for commutation, and the source for the position control will be given by gearing mode.

The clipboard operations cut, copy and paste are only possible for complete rows, i.e. for these operations the appropriate row must be selected. The deletion is possible both, row- and cellwise. A line can be selected either by clicking on the row number, or through the keyboard shortcuts + (similar to Microsoft Excel). All Edit operations are available through the Windows standard keyboard shortcuts.
