Variable jerk time via process data

This additional function can be used to specify the jerk time. For fieldbus operation, the process data length is extended by one process data word.

WARNING

Unexpected system behavior by changing the jerk time during deceleration. If the jerk is reduced (jerk time increased) during deceleration, the target position may be overrun.

May result in death, severe injuries or damage to property

• Change the jerk (jerk time) only when the machine is at idle state.

INFORMATION

When the variable jerk time is activated, no additional page appears under additional functions. No additional parameters are required to use the variable jerk time.

You can activate the additional function in the parameter group [Basic settings] under "Functions used".

The specified jerk time is not effective in the following cases:

• When the operating mode Stop (0) (FCB 02) is activated
• When the "Enable/application stop" signal (FCB 13) is removed
• When the "Enable/emergency stop" signal (FCB 14) is removed
• When an error response is active (FCB 13 or FCB 14)

In these cases, the inverter jerk time set in the parameter group [Functions] > [Monitoring functions] > [Limit values] takes effect.
