Scaling the Analog Command (Speed Mode)
The motor’s speed command is determined by the analog voltage difference
between V_REF and VGND. Use parameters ID147 (P1.040), Analog To
Velocity Scale, and ID679 (P1.081), Analog To Velocity Scale 2, to adjust the
slope of speed and its range.
Speed Mode Timing
In the above diagram, the following applies.
• ‘Off ’ signifies the contact is open while ‘On’ signifies the contact is closed.
• When the drive is in Sz mode, the speed command S1=0.
