Notes on dimensioning
• Standstill phase
• The torque (holding torque) which is generated during the standstill phase does not have to
be absorbed by the motor. In the torque diagram of the motor it can be seen that the torque
at standstill is set to zero. This torque can be taken over by the mechanical brake and is shown
in the torque diagram of the brake. The corresponding diagrams can be selected in the result
tree.
• Brake
• For the activation of the brake, the Engagement time or Disengagement time is to be taken
into consideration.
• Mechanical brake selection ( 326)
• Controller inhibit
• In order to achieve an additional relief of the motor and the inverter, the setting of the con-
troller inhibit can be activated when the motion profile is entered. Generally, controller inhib-
it is also set if the mechanical brake is activated. If controller inhibit is set, the motor at
standstill is no longer supplied with current and the effective current load is reduced.
• Mass of the payload, counterforce
• Depending on the application, a payload or counterforce can be entered for each subprofile,
so that, for instance, empty movements or wind loads can be taken into consideration.
