The parameter 4-7-1 value is “Motor”
•
Check parameters 1-2-2 and 1-2-3.
- If the temperature sensors are not connected, the values for parameters 1-2-2 “Temp 1” and/or 1-2-3
“Temp 2” is < -20
o C (< 0 o F).
• Check that temperature sensor 1 (slow speed) is connected to terminals 21 - 22, and sensor 2 (fast
speed) is connected to terminal 23 - 24.
- Drive the hoist in slow speed and check that reading of parameter 1-2-2 Temp 1 increase.
- Drive the hoist in fast speed and check that reading of parameter 1-2-3 Temp 2 increase.
• Check the parameters 3-2-2 “Mhs1” and 3-2-7 “Mhs2”.
- If the values are equal to each other, the calibration is done with only one load. (Confirm by checking the
following parameters: 3-2-3≠3-2-8, 3-2-4≠3-2-9, 3-2-5≠3-2-10).
- Perform the calibration procedure as described in this manual.
• If the parameters 3-2-7 … 3-2-10 values are negative, check the current transformers and their
connections and/or the voltage measurement connections. Pay special attention to the correct phase
order.
• If supply voltage frequency is 60Hz, check that parameter 1-2-16 is set to 60 Hz. The hoist-monitoring
unit must identify the supply voltage frequency.
