5.1.6 Electrical data
The electrical data of the available SC6 sizes as well as the properties of the brake chopper can be found in the following
sections.
Information
For the time span between two energizing processes, note that:
▪ Direct, repeat activation of the supply voltage is possible for power-on/power-off operation.
▪ A time span of > 15 must be observed between two energizing processes during continuous, cyclical power-on/
power-off operation with increased charging capacity.
Information
The STO safety function is available for safe stopping as an alternative to continuous, cyclical power-on/power-off
operation.
An explanation of the formula symbols used can be found in the chapter Symbols in formulas [}92].
