(7) Limitation in case of using High Speed HRV current control in Servo HRV3
- Servo axis control card
There are 2 types of Servo axis control card.
(a) Type A : 1 optical connector (Maximum number of axis is 8 axes.)
(b) Type B : 2 optical connectors (Maximum number of axis is 8 axes.)
How many amplifiers and units can be connected to one optical connector:
- Without ‘High Speed HRV Current control’ : 8axis+2units
- With ‘High Speed HRV Current control’: 4axis+1unit
less than 4 axes
more than 5 axes
- Servo Amplifier
In case to apply ‘High Speed HRV Current control’, servo amplifiers listed in the table 3 of page 10 is
necessary. Although, ‘High Speed HRV Current control’ becomes valid only on the axis which has 40-
130Ap current limit, 12 and 20Ap amplifier with #H can be connected to the same line of ‘High Speed
HRV Current control ‘ amplifier.
On the other hand, following amplifier can not be used on the ‘High Speed HRV Current control’ link.

- Torque of Servo Motor
During cutting cycle, torque of Motor is clamped by 70% of maximum torque.
As for rated current, as long as
α
M is used, same level as conventional system.
