MH300
12.1-10-6

10-17
Electrical Gear A

10-18
Electrical Gear B
Default: 100
Settings 1–65535
 Rotation speed = pulse frequency / encoder pulses (Pr.10-01) * Electrical Gear A / Electrical Gear
B.

10-19
Positioning for Encoder Position
Default: 0
Settings -32767–32767 pulses
 Determines the internal position in the position mode.
 Use this with the multi-function input terminal setting = 35 (enable single-point position control).
 When set to 0, it is the Z-phase position of the encoder.

10-20
Error Range for Encoder Position Reached
Default: 10
Settings 0–65535 pulses
 This parameter determines the range for the internal positioning position reached.
Example:
When you set the position for Pr.10-19 (Positioning for Encoder Position) and Pr.10-20 to 1000, it
reaches the position if the position is between 990-1010 after positioning.

10-21
Filter Time (PG2)
Default: 0.100
Settings 0.000–65.535 sec.
 When you set Pr.00-20 to 4, the system treats the pulse command as a Frequency command.
Use this parameter to suppress the speed command jump.
10-24
FOC & TQC Function Control
Default: 0
Settings 0–65535
 Only bit = 0 is used for closed-loop, other bits are used for open-loop.
bit Description
0
ASR controller under torque control. 0: use PI as ASR; 1: use P as ASR
1–10
NA
11
Activates DC brake when executing the zero torque command. 0: ON; 1: OFF
12
FOC Sensorless mode, crossing zero means the speed goes from negative to positive
or positive to negative (forward to reverse direction or reverse to forward direction).
0: determined by stator frequency; 1: determined by speed command
13 NA
14 NA
15
Direction control in open-loop status.
0: Switch ON direction control; 1: Switch OFF direction control
