Variable jerk

The additional function "variable jerk" allows to specify the jerk. For fieldbus operation, the process data length is extended by one process data word.

INFORMATION

The set jerk is applied only when the axis is at an idle state (profile generation not active).

INFORMATION

When using the jerk time, the stop by setpoint function must be activated. This is the only way to ensure jerk-free travel until standstill.

For the states listed below, the preset jerk does not work. In these cases, the "Jerk time" of the inverter configured under "Application limits" in the Limit values submenu of the "Monitoring functions" configuration menu is effective.

• When selecting the default mode (value "0")
• When the "Enable/application stop" signal is removed (FCB 13)
• When the "Enable/emergency stop" signal is removed (FCB 14)
• With an active fault response (FCB 13 or FCB 14)
