Motion Parameters
Changing the maximum value of acceleration and deceleration for SGDV SERVOPACKs
When the SERVOPACK parameter Pn833.0 is set to 1 (Accel/Decel Constant Selection = Uses Pn834 to Pn840), a
wilder range of speed for acceleration and deceleration can be obtained by raising the upper limit of acceleration and
deceleration for the following motion commands.
• Positioning (POSING)
• External input positioning (EX_POSING)
• Zero Point Return (ZRET)
• JOG operation (FEED)
• STEP operation (STEP)
After communications have been established between the SVB module and SERVOPACK, the SVB module reads the setting
of Pn833.0 and changes the applicable parameters. Use the following SERVOPACK parameters to set the
acceleration and
deceleration.
• Parameters to set acceleration and deceleration when Pn833 = n. 0
• Parameters to set acceleration and deceleration when Pn833 = n. 1
To enable the new setting for Pn833, the SERVOPACK must be restarted.
When connecting SGDV SERVOPACKs and executing self-configuration for the first time, set Pn833.0 to 1.
Example: Total time until the reference reaches the rated 3000 min -1 when using a 17 bit encoder.
The maximum acceleration of Pn80B: 65535 × 10000 pulse/s 2 = 10 ms
The maximum acceleration of Pn836: 20971520 × 10000 pulse/s 2 = 3 ms
