*1 This is regulated according to the temperature 30 mm 1.181" below the center of the control panel unit.
*2 Conforms to JIS B 3502 and IEC61131-2. Number of scans : 10 times (100 minutes) in each of the X, Y, and Z directions
*3 The settings can be configured so that auto reset is not performed.
*4 Only open collectors are supported. Line drivers cannot be supported.
*5 You can set the target device by clicking “CPU system setting” and then “Power off holding” in KV STUDIO.
*6 Reference value of input current.
*7 The input response time corresponding to the input time constant can be calculated as shown below. (Response time) = (Circuit delay of the input circuit) + (Delay by the digital filter)
Example : Maximum response time when the input time constant is set to 500 µs
OFF to ON : 30 µs (circuit delay) + 400 µs (digital filter) = 430 µs
ON to OFF : 50 µs (circuit delay) + 400 µs (digital filter) = 450 µs
*8 Normal : 10 ms, When the HSP instruction is used : 10 µs
When CR2305 is turned ON : 10 µs to 10 ms, eight-level switching is possible (set with CM1620) Can also be set from the Unit Editor.
*9 If an overcurrent occurs, the protection operation (output turned OFF) and automatic recovery are repeated for all outputs
within the shared common until the cause of the problem is removed.
