STO alarm 1) When the hundreds of P11.16 is set to 1, the STO alarm is locked As shown in below fig 1, When H1 and H2 are ‘OFF’ during operation (safety function is required), the drive enters safety mode and stops output. STO alarm will only be disappeared once reset action is valid. External running command need to be reset for the drive to execute running command again. Fig 1 2) When the hundreds of P11.16 is set to 2, the STO alarm will not be locked As shown in below fig 2, alarm non-lock means when STO appears, the STO alarm will disappear automatically after state restoration, which requires no reset action. After reset of external running command, the drive will execute running command again. Fig 2 STL1 fault As shown in below fig 3, when the hardware circuit of safety circuit 1 is abnormal while that of H2 signal is normal, namely, when H1 is abnormal during operation (safety function is required), the drive enters safety mode and stops output no matter whatever the running command is. Despite of reset commands and external running command reset, the drive will not execute running command again, and it is STL1 alarm lock all the time. Fig 3 STL 2 fault As shown in below fig 4, when the hardware circuit of safety circuit 2 is abnormal while that of H1 signal is normal, namely, when H2 is abnormal during operation (safety function is required), the drive enters safety mode and stops output no matter whatever the running command is. Despite of reset commands and external running command reset, the drive will not execute running command again, and it is STL2 alarm lock all the time. Fig 4
