P47 Electromag
netic brake
ON delay

It defines the motor enable lock shaft (input terminal
SON from OFF to ON);

Delay time to open brake. (output terminal BRK from
OFF to ON)

This parameter is set to ensure the switch from brake
lock shaft to motor enable lock shaft to be stable when
the motor with brake is connected to the power.

P48 Electromag
netic brake
OFF delay

It defines the motor enable removal (input terminal
SON from ON to OFF);

Delay time to close brake. (output terminal BRK from
OFF to ON)

This parameter is set to ensure the switch from motor
lock shaft to brake lock shaft be stable when the motor
with brake is disconnected to the power;

This parameter can be prolonged when the motor is
from high-speed operation to stop, to enhance the effect
of rapid deceleration.

P49 Zero speed
clamp-on The motor will stop when the value is less than this
parameter. 0-2000
P50 Current
loop gain

Current loop proportional gain, and when motor current
is bigger, its set value should be adjusted to be bigger
appropriately, and the operational sound of motor
operation will be louder. Generally it doesn’t need to be
adjusted.

Default value is 600.
10-4000
P51 Current
loop
integral

Current loop integral gain, and when motor current is
bigger, its set value should be adjusted to be bigger
appropriately, and the operational sound of motor
operation will be louder. Generally it doesn’t need to be
adjusted.

Default value is 150.

P52 Encoder
lines

Only if motor type is set to be
（
P2=9999
）
, this
parameter will be valid.

Encoder lines of input motor is generally 1024,2048,
2500, 3000, 5000.

Please note that this parameter will be valid after it is
modified and saved, and then restart the machine;

Default value is 2500.

P53 Encoder
type 
Only if motor type is set to be
（
P2=9999
）
, this self-
defined parameter will be valid.

Set value as 0 refers to general non-cable saving
encoder; set value as 1 refers to cable saving encoder;

Please note that this parameter will be valid after it is
modified and saved, and then restart the machine;

Default value is 0.

P54 Pole-pairs 
Only if motor type is set to be
（
P2=9999
）
, this self-
defined parameter will be valid.

Set value refers to the number of pole-pairs;

Please note that this parameter will be valid after it is
modified and saved, and then restart the machine;

Default value is 4.
