Status
3.
Activate STO
3.1. Activate STO while the motor is running.
3.2.
Check the following:
When controlled via terminals STO_A and STO_B on Power Module PM330P-2
• The inverter signals:
r0002 = [44] Switching on inhibited – connect 24 V to terminal STO (hardware)
• The inverter signals neither faults nor alarms.
• Motor coasts down. Wait until motor is at a standstill.
3.3. Check the status LEDs of the safety relay
(here in the example, a 3SK1112-… or 3SK112x-…)
• LED (1) DEVICE = green
• LED (2) OUT = off -> 3SK1 output circuit open
• LED (3) IN = off -> 3SK1 switch-on (close) conditions not satisfied
– Here, input circuit closed
• LED (4) SF = OFF
4.
Deactivate STO
4.1.
Deactivate STO.
4.2.
Check the following:
• STO is not active (r0002 ≠ 44).
(e.g. R0002 = [31] Ready for switching on – set "ON/OFF1" = "1/0" (p0840)
• The inverter signals neither faults nor alarms.
4.3. Check the status LEDs of the safety relay
(here in the example, a 3SK1112-… or 3SK112x-…)
• LED (1) DEVICE = green
• LED (2) OUT = green-> 3SK1 output circuit closed
• LED (3) IN = green-> 3SK1 switch-on (close) conditions satisfied
– Input circuit closed
– Feedback circuit closed
– Start button where necessary actuated
• LED (4) SF = OFF
