In this case, if the required speed at the load side is 12000 rpm, and speed at the motor side
should be 6000 rpm, then the pulse-train command given by the controller is 102400 pulse/sec [=
(1024 × 6000) ÷ 60 = 102400].
 If you set the mechanical gear ratio incorrectly, overshot may occur.
 This function is only valid for single-point positioning.

Treatment for Encoder / Speed Observer Feedback Fault
Default: 2
Settings 0: Warn and continue operation
1: Fault and ramp to stop
2: Fault and coast to stop

10-09
Detection Time of Encoder / Speed Observer Feedback Fault
Default: 1.0
Settings 0.0–10.0 sec. (0: Disabled)
 When there is an encoder loss, an encoder signal error, a pulse signal setting error or a signal
error, if the duration exceeds the detection time for the encoder feedback fault (Pr.10-09), the
encoder signal error occurs. Refer to Pr.10-08 for encoder feedback fault treatment.
 When the speed controller signal is abnormal or the direction of operation and speed observer
are different, if time exceeds the detection time for the encoder feedback fault (Pr.10-09), reverse
direction of the speed feedback fault (SdRv, fault no. 68) occurs. Refer to chapter 14 for the
troubleshooting.

Encoder / Speed Observer Stall Level
Default: 115
Settings 0–120% (0: Disabled)
 Determine the maximum feedback signal allowed before a fault occurs. The maximum operation
frequency for Pr.01-00 = 100%

10-11
Detection Time of Encoder / Speed Observer Stall
Default: 0.1
Settings 0.0–2.0 sec.

Encoder / Speed Observer Stall Action
Default: 2
Settings 0: Warn and continue operation
1: Fault and ramp to stop
2: Fault and coast to stop
 When the drive output frequency exceeds the setting of the encoder / speed observer stall level
(Pr.10-10), and if the accumulation time exceeds the detection time of speed observer stall
(Pr.10-11), then the over speed rotation feedback (SdOr, fault no. 69) fault occurs. Refer to
Chapter 14 for fault treatment.
