0x0002：reverse running；
0x0003：forward jog；
0x0004：reverse jog；
0x0005：free stop；
0x0006：decelerating stop；
0x0007：immediate stop；
0x0008：fault reset；
0x7001
Communication speed given. The unit of this register can be set by
P30.14。
0.01%（-100.00% ~ 100.00%）

0x7003
Communication upper frequency given. The unit of this register can
be set by P30.14.
Different units range same as 0x7001.
0x7004
Torque mode speed limit. The unit of this register can be set by
P30.14.
Different units range same as 0x7001.
0x7005

PID setting source.0.01%（-100.00% ~ 100.00%）
0x7008
PID feedback source 0.01%（-100.00% ~ 100.00%）
0x7009
VF separation voltage given.0.1%（0~ 100.0%）
0x700A
External fault setting
0x700B
DO status setting. When the DO function (please refer to P07.01 ~
P07.10) is set to 0 (no function), its status comes from the setting of
the communication dedicated register, and the corresponding bit of 1
means it is valid. The bits of this register are defined as follows:
Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0
RL2 RL1 DO2 DO1
Bit15 Bit14 Bit13 Bit12 Bit11 Bit10 Bit9 Bit8
