*1 The temperature below the unit center (30 mm 1.18″) inside a control panel.
*2 Conforms to JIS B 3502 and IEC61131-2. Scan times: 10 times (100 minutes) in each of the X, Y, and Z directions
*3 You can also configure the settings so that automatic reset is not used.
*4 Only open collectors are supported. Line drivers are not 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 10 μs
OFF to ON: 2 μs (circuit delay) + 2 μs (digital filter) = 4 μs
ON to OFF: 2 μs (circuit delay) + 2 μs (digital filter) = 4 μs
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 If an overcurrent occurs, 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.
