Step 2: Maintain balanced load on Car and CWT side and locate the Elevator car in midway of the
Shaft and Make sure the free movement of Car and CWT in the guide rail
Step 3: Verify the parameter (F1-01~F1-05) values that are correctly set to the actual motor nameplate
Step 4: Set the parameter F1-00=0 according to the actual encoder mounted on Motor shaft,
Set the value 0: Sin/Cos and F1-12=2048 PPR for Sin/Cos Encoder
Step 5: For Inspection speed setting, use parameter F3-11=0.250mps. Please refer content of 5.2 (Page-18)
for MCB’s LED sequence for Inspection operation
Step 6: Select the parameter F1-11=1 and press button, now operating LED keypad shows ‘TUNE’
Step 7: Using the control panel Inspection button, press UP/DOWN button, now the Synchronous motor
runs few (One & two)rotation. During tuning process, keep pressing the UP/DOWN button until
the Tuning gets finished. NICE 1000 system calculate the following parameters
F1-06Encoder initialized angle
F1-08Wiring connection
F1-09ADC sampling delay
F1-10Selection check of encoder’s signal
Once tuning process is over, ‘TUNE’ display goes off and LED keypad displays the Inspection
Reference speed value.
Step 8: Follow the above tuning process more than 3 times and verify the parameter F1-06 value that the
Error tolerance is within the range of ±5%
5.6.2.2 Tuning without Load on Hoist Motor :
Step 1: Separate the load from the motor (remove ropes from hoist machine)
Step 2: Set F0-01=0, now the control mode is selected to the operating LED keypad control
Step 3: Make sure that the machine Brake is powered ON for free movement of Machine rotor
Step 4: Verify the motor parameter (F1-01~F1-05) values are correctly set as per the actual motor
Nameplate and Encoder details (F1-00=0 & F1-12=2048)
Step 5: Select parameter F1-11=2 and press button, operating LED keypad display shows
‘TUNE’.
Then press button on Keypad. Now the tuning process starts and NICE 1000 calculate the following
parameters during the tuning process, F1-06, F1-07, F1-08, F1-09 and F1-10.
Once tuning process is over, ‘TUNE’ display goes off and LED keypad displays to normal status.
Step 6: Follow the above tuning process more than 3 times and verify the parameter F1-06 value that the error
tolerance is within the range of ±5%
