10 Speed Feedback Control Parameters
 You can set this parameter during operation.
10-00
Encoder Type Selection
Default: 0
Settings 0: Disabled
1: ABZ
3: Resolver 1x PM encoder
5. Pulse input (MI7)
 When you use the MI7 single-phase pulse input function, you must use it with Pr.00-20 = 4,
Pr.10-00 = 5 and Pr.10-16 = 5
 When you use the MI6 and MI7 two-phase pulse input function, you must use them with Pr.00-20
= 4, Pr.10-00 = 0, Pr.10-16 = 1–4
 When you use MI7 single-phase pulse input as speed feedback, you must use it with Pr.10-00 =5
and Pr.10-02 = 5. The drive calculates the MI7 single-phase pulse input speed when the control
modes are VF, VFPG, SVC, IM / PM FOC Sensorless, or IM / PM TQC.
 When you use MI6 and MI7 two-phase pulse input as speed feedback, you must use them with
Pr.10-00 = 5 and Pr.10-02 = 1–4. The drive calculates the MI6 and MI7 two-phase pulse input
speed when the control modes are VF, VFPG, SVC, IM / PM FOC Sensorless, or IM / PM TQC.
10-01
Encoder Pulses per Revolution
Default: 600
Settings 1–20000
 This parameter sets the encoder pulses per revolution (ppr). It is a feedback control signal source
when using PG. The encoder sets the number of pulses for the motor rotating through one rotation.
The A
/ B phas
e cycle generates the pulse number.
 This setting is also the encoder resolution. The speed control is more accurate with higher
resolution.
 If you set this parameter incorrectly, it may cause motor stall, drive over-current, or a magnetic
pole origin detection error for the PM motor in closed-loop control. When using the PM motor, you
must perform the magnetic pole origin point detection (Pr.05-00 = 4) again if you modify the
content of this parameter.
10-02
Encoder Input Type Setting
Default: 0
Settings 0: Disable
1: Phas
es A and B are pulse inputs, forward direction if A-phase leads B-
phase by 90 degrees.
