Fail-safe digital input 1 (DI 4 and DI 5) • If you have enabled the basic safety functions, DI 4 and DI 5
form the fail-safe digital input.
• Maximum input voltage 30 V, 5.5 mA
• Response time:
– Typical: 5 ms + debounce time p9651
– Typical, if debounce time = 0: 6 ms
– Worst-case scenario: 15 ms + debounce time
– Worst case, if debounce time = 0: 16 ms
You require a license to enable several inverter functions:
● License for the following extended safety functions with speed monitoring:
– Safe Stop 1 (SS1)
– Safely Limited Speed (SLS)
– Safe Direction (SDI)
– Safe Speed Monitor (SSM)
Order number: 6SL3074-0AA10-0AA0.
● License for the "Basic positioner" function
Order number: 6SL3074-7AA04-0AA0.
The license is supplied on a memory card. To operate the inverter, the card with the license
must be inserted. The license key is saved in a non-volatile fashion on the card; it cannot be
transferred to other cards
The inverter uses an inserted license card also as memory card to back its settings.
Part number is 6SL3246-0BA22-1PA0. Model number is CU250S-2 DP
