Control of the safety functions
5.5 Communication failure via PROFIsafe or with TM54F
Drive response
For a communication failure, the converter responds corresponding to the settings of the
ESR function module.
For communication failure, a maximum delay time of (p9580) 800 ms can be set. After this
time has elapsed, the frequency converter activates the "Safe Torque Off" function.
Depending on the setting, either stop responses or safety functions can prevent the ESR
response. You must set the safety functions as follows in order that you do not influence the
ESR response:
Func- Precondition for the ESR response after communication failure
tion
SLP As SLP response, a STOP is parameterized with delayed pulse cancellation when the bus
fails
SLS As SLS response, a STOP is parameterized with delayed pulse cancellation when the bus
fails
SDI As SDI response, a STOP is parameterized with delayed pulse cancellation when the bus fails p9566 ≥ 10
SLA As SLA response, a STOP is parameterized with delayed pulse cancellation when the bus
fails
--- Adequate STOP F to STOP B transition time if additional faults occur when the communica-
tion fails
--- Adequate STOP F to STOP A transition time if additional faults occur when communication
fails.
--- Check whether the effective setpoint speed limiting (CO: r9733) is set to zero when STOP F is
active.
