Operating behavior

Firmware version 12 of the basic device covers the different operating behaviors of previous firmware versions.

You can use the Interrupt F-communication parameter to set the different operating behaviors. The setting of the operating behavior thus ensures compatibility with previous firmware versions.

The following table shows the operating behavior of the basic device for firmware versions ≥ 12.0:

Safety option	Parameter setting	Operating behavior
STO connection via terminals, no safety card	–	You can operate the drive with the prioritized terminal control as long as the safety sub-function is deactivated via the STO signals at the terminals.
Safety card without safe inputs	Interrupt F-communication = YES (default)	When activating the prioritized terminal control, F-communication with the safety card is stopped. The communication timeout of the safety card activates the safety sub-functions and inhibits the drive. You can deactivate the safety sub-functions using the F‑PO muting function and thus enable the drive again. You can activate the "Muting F-PO" function by starting emergency mode with the CBG21A keypad. INFORMATION SEW-EURODRIVE recommends that you DO NOT use this parameter setting in conjunction with a safety card without safe inputs.
Safety card without safe inputs	Interrupt F-communication = NO	When activating the prioritized terminal control, F-communication with the safety card is continued. You can operate the drive with the prioritized terminal control as long as the safety sub-functions are not activated via the control signals at the safety card.
Safety card with safe inputs	Interrupt F-communication = YES (default)	When activating the prioritized terminal control, F-communication with the safety card is stopped. The communication timeout of the safety card activates the safety sub-functions and inhibits the drive. You can deactivate the safety sub-functions using the F‑PO muting function and thus enable the drive again. You can activate the "F-PO muting" function with appropriately configured safe digital inputs. INFORMATION SEW-EURODRIVE recommends that you use the prioritized terminal control in conjunction with this parameter setting only to control the drive independently of the control via F-communication (e.g. for emergency mode).
Safety card with safe inputs	Interrupt F-communication = NO	When activating the prioritized terminal control, F-communication with the safety card is continued. You can operate the drive with the prioritized terminal control as long as the safety sub-functions are not activated via the control signals at the safety card.
