CONTROL
HRV2
FSSB slave number
4 / FSSB
Applied slave
αi series servo amplifier
α(HV)i series servo amplifier
Applied Motors
Motor with multiple windings (4 or more windings)
Tandem Linear motors with single scale
NOTE
1. To use PDM, it is necessary to set up HRV3 but, and the characteristic of the axis which uses
PDM is corresponding to HRV2
2. The peak current of all servo amplifiers connected to PDM must be the same.
3. The available slave number of PDM is only four.
4. In 2 winding motor drive, please use the method of torque tandem control, without using PDM
as usual.
5. In the case of 4 winding motor drive, one PDM with 4 slave number setting is used per motor.
6. In the case of 8 winding motor drive, two PDM with 4 slave number setting are used per motor,
and torque tandem control is applied to two sets of PDM.
(3) Parameter setting
Please set following parameters for PDM axis. (Please refer to PARAMETER MANUAL B-65270)
1) Please initialize the servo parameter by the motor ID for HRV2.
2) Please set the function bit HRV3(No.2013,bit0) to 1
#7 #6 #5 #4 #3 #2 #1 #0
No. 2013 HRV3
HRV3 (#0) 1:Uses high-speed HRV current control.
0:Does not use high-speed HRV current control.
3) Please set No.2165 to 0, in order to avoid the alarm “Motor/Amplifier mismatch”
No.2165 Please set to 0.
