8-38
10-00
Encoder Type Selection
Default: 0
Settings 0: Disabled
8: Tamagawa
 Pr.10-00 = 8 (Tamagawa), encoder input type (Pr.10-02) is set to 1. The default of encoder
pulses per revolution (Pr.10-01) is 32768.
10-01
Encoder Pulses per Revolution
Default: 600
Settings 1–65535
 Pr.10-00 = 8 (Tamagawa), the default for Pr.10-01 is 32768, which is only applied to Tamagawa
encoder with 17bit single-turn revolution.
 When the single-turn resolution of communication encoder is not 17 bit, you can change the
setting for Pr.10-01. Divide the actual encoder single-turn resolution by 4 before the setting. For
example: when the communication encoder resolution is 14 bit (16384), Pr.10-01 = 4096. This
setting method does not affect the encoder resolution, it is used only to comply the old ABZ
incremental encoder setting rules.
 Currently support the encoder resolution to maximum 17 bit.
10-02
Encoder Input Type Setting
Default: 0
 When Pr.10-00 = 8 (Tamagawa), Pr.10-02 is set to 1.
 When Pr.10-00 = 8 (Tamagawa): if the drive appears PGF1 error when pressing RUN under the
PG mode, switch any two of the motor UVW wires then restart the operation. If it is PM, you
need to re-execute the dynamic test for PM magnetic pole (Pr.05-00 = 4).
10-03
Frequency Division Output Setting (Denominator)
Default: 1
Settings 1–255
 When the encoder input type is Tamagawa (Pr.10-00 = 8), set Pr.10-03 as indicated below:
One turn of the encoder, PG card single-phase pulse output (A-phase and B-phase) =
(
Encoder single-turn resolution

) ÷ 4。
For example: When the encoder resolution is 131072 and Pr.10-03 = 1, the PG card single-turn
pulse output for one turn of the encoder: (

2
ሺ
10-03
ሻ
+5
) ÷ 4 = (131072 ÷ 64) ÷ 4 =
512, both A-phase and B-phase output 512 pulses, the phase difference is 90 degrees.
 When Pr.10-03 value + 5 > 30, the program processes as 30.
For example: Pr.10-03 = 50, the PG card single-phase pulse output (A-phase and B-phase) for
one turn of the encoder is (

) ÷ 4。
NOTE: Encoder single-turn resolution = Pr.10-01 × 4.
