Table 2: Setting for A1 Encoder Pulses for
different motor types
c. Ropes on PPR calculation:
i. Mathematically calculate
the Encoder Pulses (A1)
using the equation below.
The diameter of the rider
wheel is either 37.3mm
(1.469in) or 75mm
(2.952in) depending on
which one you have.
𝐸𝑛𝑐𝑜𝑑𝑒𝑟 𝑃𝑢𝑙𝑠𝑒𝑠 (𝐴1)
= 𝐸𝑛𝑐𝑜𝑑𝑒𝑟 𝑁𝑎𝑚𝑒𝑝𝑙𝑎𝑡𝑒 𝑃𝑃𝑅
𝑑𝑖𝑎𝑚𝑒𝑡𝑒𝑟
𝑟𝑜𝑡𝑜𝑟
𝑑𝑖𝑎𝑚𝑒𝑡𝑒𝑟
𝑟𝑖𝑑𝑒𝑟 𝑤ℎ𝑒𝑒𝑙
5. Verify that both Encoder Pulses (A1)
and Enc PPR Low (A1) are set to the
same value for low speed operation
(such as the construction phase).
6. Before the motor can run, a rotor
alignment to find the motor poles
needs to be performed. The 3
methods to find the motor pole are:
High Frequency (HF) Injection, Open-
Loop Align, and Auto-Align beginning
on page 11 in PM Alignment
Procedure.
NOTE:
HF injection is recommended
because it can locate the motor’s
poles more reliably on these motors
than Auto-Align.
7. Perform an
auto-tune
on the drive so
that the drive has a more accurate
motor model outlined in
on page 15.
NOTE:
skip step 8 if the motor was
running at high speed with ropes off
8. After the motor can run up/down the
hoist at high speed, fine tune the
Encoder Pulses (A1) and Enc PPR
Low (A1) by entering the number in
the D1 ‘Measured PPR’ into these
parameters.
NOTE:
The number set in the Encoder
Pulses (A1) HAS to be the value
displayed in D
1 ‘Measured PPR’ at
high speed. The number set in the Enc
PPR Low (A1) HAS to be the value
displayed in D1 ‘Measured PPR’ at low
speed.
Refer to Troubleshooting page 16 if
the drive faults out
