Mode 14: positive direction to torque limit
Procedure:
1. Movement in a positive direction with reduced torque and profile data set 1.
2. The reference is set if the two following conditions for the time set in
C02650 are fulfilled at the
same time:
• The current speed is lower than the threshold for standstill detection set in C00019 .
• Current torque is greater than the torque limit set in C02649 ("Homing to end stop").
3. Absolute positioning to target position ( C02643 ) with profile data set 2 (if C02641 = "0").
Mode 15: negative direction to torque limit
Procedure:
1. Movement in a negative direction with reduced torque and profile data set 1.
2. The reference is set if the two following conditions for the time set in
C02650 are fulfilled at the
same time:
• The current speed is lower than the threshold for standstill detection set in C00019 .
• Current torque is greater than the torque limit set in C02649 ("Homing to end stop").
3. Absolute positioning to target position ( C02643 ) with profile data set 2 (if C02641 = "0").
Mode 100: Set reference directly
During the drive is at standstill, the measuring system is set by means of the home position
parameterised in C02642 .
