- Check “Ain Value” (V2.1.12.3) is back at 0 V.

2.14 Test run without load

- Display monitoring parameter “Frequency reference” (V4.9) on both drives.

- In EP mode, accelerate the hoist (up and down) to any speed (between the minimum speed and maximum speed)

and verify both drives display the same frequency reference (± 0.25 Hz) when constant speed is reached.

- Lower the frequency value of “Max Freq S1” (P2.2.10) of one drive temporarily about 20 Hz – run in up direction and

verify the “faster hoist” will slow down after accelerating. Again, check that both drives display the same frequency

reference. Return “Max Freq S1” back to its original value.

- Run both hoists up in tandem mode and stop one hoist by disconnecting the voltage from its upper stop limit terminal

(X1:41) – the other hoist must stop and display “Multicare Fault” (F70).

- Reconnect the voltage back to terminal X1:41.

- Repeat the same test with the other hoist.

- Check both hoists operate normally (in tandem mode and single mode) when reaching the slow-down and end stop

limit in both directions.
