358 Safe torque off function
Safety data
The safety data for the Safe torque off function is given below.
Note: The safety data is calculated for redundant use, and does not apply if both STO
channels are not used.
• The following temperature profile is used in safety value calculations:
• 670 on/off cycles per year with T = 71.66 °C
• 1340 on/off cycles per year with T = 61.66 °C
• 30 on/off cycles per year with T = 10.0 °C
• 32 °C board temperature at 2.0% of time
• 60 °C board temperature at 1.5% of time
• 85 °C board temperature at 2.3% of time.
