AC30 series Variable Speed Inverter
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:
0V to +5V
Recommended input voltage for high level: +21.6V to +26.4V
Typical input threshold voltage: +10.5V
Indeterminate input range: +5V to +15V. Function is undefined.
Absolute maximum input voltage: -30V to +30V
Typical input current @ 24V 9mA
Fault detection time 4 : 2.3sec typical;
< 1.6sec will not generate a fault
> 3.0sec will generate a fault.
Response time
5
> 2ms
6ms typical
< 10ms
Conditions in which the STO inputs are operative: All, i.e. STO cannot be disabled in any condition
Output Specification
OFF state:
Maximum applied voltage: ±30V (X10/06 relative to X10/05)
Leakage current: Less than 0.1mA.
ON state:
Maximum output current: 150mA
Overcurrent protection: Included
Resistance between output terminals: Less than 6
Ω
.
WARNING
WIRED CONNECTIONS TO TERMINALS X10/01, X10/03, X10/05 AND X10/06 MUST BE LESS THAN 25 METRES IN LENGTH
AND REMAIN WITHIN THE CUBICLE OR DRIVE ENCLOSURE. PARKER IS NOT LIABLE FOR ANY CONSEQUENCES IF
EITHER CONDITION IS NOT MET.
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
