STO Technical Specification

INPUTS SPECIFICATION

STO A Input and STO B Input comply with IEC61131-2. Note: inputs do not have hysteresis.
Recommended input voltage for low level:
Recommended input voltage for high level:
Typical input threshold voltage:
Indeterminate input range:
Absolute maximum input voltage:
Typical input current @ 24V
Fault detection time
Response time
5
Conditions in which the STO inputs are operative:
4
A fault is defined in this context as STO A Input and STO B Input being sensed in opposite logic states.
5
Response time is the time from the first STO input becoming active (voltage level is low) until torque production has ceased
