*1 This is the guaranteed range of the system (excluding the specially mentioned values of each unit and cassette).
*2 This is regulated according to the temperature 30 mm below the center of the control panel unit.
*3 The range guaranteed as a system (excluding items specially noted for the units and cassettes).
*4 These specifications correspond to situations in which the unit is mounted on a DIN rail and in which the unit is mounted on the panel directly.
*5 Conforms to JIS B 3502 and IEC61131-2. Number of scans : 10 times (100 minutes) in each of the X, Y, and Z directions
*6 You can also configure the settings so that automatic reset is not used.
*7 Only open collectors are supported. Line drivers are not supported.
*8 You can set the target device by clicking “CPU system setting” and then “Power off holding” in KV STUDIO.
*9 Reference value of input current.
*10 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
*11 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.
*12 Sink output types use MOSFET (N-ch) output. Source output types use MOSFET (P-ch) output.
*13 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.
