• The motor rotates in a different direction than expected.
To use the Rotation Direction Trouble Shoot function, select [Menu] > [Diagnostic Tools] > [Rotation Direction
Trouble Shoot] from the HOME screen. Select a problem to solve and [Execute trouble shoot], then push
Refer to the Technical Manual for more information about this function.

Setting the Encoder (Pulse Generator)
Encoder Resolution Setup
Set the encoder resolution (incremental signal in case of absolute encoders with Sin/Cos tracks) in F1-01
[Encoder 1 Pulse Count (PPR)].
Encoder Rotation Direction Setup
Do these steps to make sure that the encoder rotation direction is set up correctly in the drive.
• When information about the signal sequence of the encoder is available:
– Check the sequence of encoder phases A and B when the motor drives the elevator in the Up direction.
– If the encoder A phase leads phase B, set F1-05 = 0 [Encoder 1 Rotation Selection = Pulse A leads in Up
Direction].
– If the encoder B phase leads phase A, set F1-05 = 1 [Pulse B leads in Up Direction].
• When information about the signal sequence of the encoder is not available:
– Manually turn the motor in the elevator Up direction while you check the value of U1-05 [Speed Feedback].
– If the value in U1-05 is positive, the encoder direction is correct.
– If the value in U1-05 is negative, change the setting of F1-05.
Note:
Always do the motor rotation direction setup before you set the encoder rotation direction. Refer to
on page
25.

Keypad Display Unit Selection
You can use o1-03 [Speed Display Unit Selection] to choose between different display units for speed-related
parameters and monitors, acceleration and deceleration ramps, and jerk characteristics. Use the table below to
determine the correct o1-03 setting for your application.
o1-03 Setting
0 [0.01 Hz]
1 [0.01% (100% = E1-04)]
2 [Revolutions Per Minute (RPM)]
3 [User Units (o1-10 & o1-11)]
4 [Elevator Unit1 - m/s, s, s]
5 [Elevator Unit2 - m/(s, s^2, s^3)]
6 [Elevator Unit3-ft/(min,s^2,s^3)]
If you want to use settings 4 to 6, you must program certain mechanical data to the drive before you change o1-03.
1. Correctly set the motor data. Make sure that the settings for E1-04 [Maximum Output Frequency] and E2-04
[Motor Pole Count] or E5-04 [PM Motor Pole Count] are correct.
2. Set up the elevator mechanics:
a. Use dedicated mechanical data:
i. Set the traction sheave diameter in mm units to o1-20 [Sheave Diameter].
ii. Set the correct roping to o1-21 [Roping Ratio].
iii. When you use a geared machine, set the gear ratio (n
Gear Ratio]. When you use a gearless machine, set o1-22 = 1.0.
iv. Set o1-03 = 4, 5, or 6. The drive will automatically change the unit and setting values of related
parameters.
