Parameters
4-59
Speed feedback filter time constant [P1-11]: If the speed of the motor changes because of vibration
of the drive system, or vibration occurs due to gain when there is too much load inertia, you can
control the vibration by applying a filter to speed feedback. If you set too great a value, speed
responsiveness will be reduced and thus the power of control will be compromised.
* Recommended value = 0 to speed integral time constant [P1-08]/10
(4)
Torque Command Filter Time Constant Setting [P1-12]
You can improve the stability of command signals by setting a digital filter for analog torque
command voltage. If you set too great a value, responsiveness for torque commands will
be reduced. It is important to set an appropriate value for your system.
(5)
Torque Limit Setting [P1-13], [P1-14]
You can set maximum torque limits for forward rotation [P1-13] and for reverse rotation [P1-
14] separately. The setting is displayed as a percentage of the rated torque and the standard
is 300 [%].
(6)
Gain 1<->Gain 2 Transfer Mode Setting [P1-15] 0x0F (DIGIT 1)
Set speed gain transfer mode. [0x0F (DIGIT 1)]
0: Use only gain 1.
1: ZSPD auto gain transfer
In case of zero speed, transfer from gain 1 to gain 2.
In the opposite case, transfer from gain 2 to gain 1.
2: INPOS auto gain transfer
In case of IN position, transfer from gain 1 to gain 2.
In the opposite case, transfer from gain 2 to gain 1.
3: Manual gain transfer
When the gain 2 contact is on, transfer from gain 1 to gain 2.
In the opposite case, transfer from gain 2 to gain 1.
