Acceleration
Time
Constant
The set value means the acceleration time of motor ranging from
0r/min to 1000r/min
The acceleration and deceleration have a linear feature.
Only valid for speed control mode, invalid for position control mode.
If the drive unit is used together with external position loop, thi
s
parameter shall be set as 0.

Deceleration
Time
Constant
The set value means the deceleration time of motor ranging from
0r/min to 1000r/min
The acceleration and deceleration have a linear feature.
Only valid for speed control mode, invalid for position control mode.
If the drive unit is used together with external position loop, thi
s
parameter shall be set as 0.

Numerator of
Output
Electronic
Gear Ratio
Feedback pulse from each coil of the encoder will be output
through the gear within the drive unit. E.g., there are 2500 pulses in
each coil of the encoder, setting PA41/42=4/5, then the A and
B-phase signals output from the drive unit will be 2500 X
PA41/PA42=2000 pulses/coil.

Gear Ratio
This parameter must be more than or the same with parameter
No.41.

Choice of
Speed
Command
Whether the operation speed is from internal speed or analog
command:
0 Internal speed
1 Analog command
0~1

High Speed
AD Zero
Point
When restoring default value, this parameter will not be recovered. 412~1600
45
Low Speed
AD Zero
Point
When restoring default value, this parameter will not be recovered. 412~1600

0 Normal
1 Opposite to the analog speed command
2 Opposite to the output pulse rotation direction
3 Opposite to both.

Analog
Command
Gain
Analog command is transited to speed gain.

Anti-jamming
Scope for
Analog
Command
The function is the same with parameter No.33, but the function
range includes all speeds rather than zero speed only. It is
recommended that this parameter not be used simultaneously
together with parameter No.33.
0～1000

Choice of
Zero
Adjustment
Channels for
Analog
Speed
0 Low speed AD for low speed and high speed AD for high speed.
1 High speed AD for both high and low speed
This parameter is used only for AD zero adjusting: to improve the
resolving power of analog command, AD switch with different
multiplying factors are employed for high and low speed. First set
this parameter as 1 to adjust zero point for high speed AD, then set
the parameter as 0 to adjust zero point for low speed AD.

Analog
Command
Transition
Mode
0 Speed AD is transited to speed command with curve of second
order
1 Speed AD is transited to speed command with straight line.
