Uni-directional Speed Setpoint
This connection provides a Uni-Directional Speed Setpoint for non-reversing applications and the 2 Quadrant
controller (591+):
Maximum forward speed setpoint (+100%) = Terminal B3, +10V input
Zero speed setpoint (0%) = Terminal B1, 0V input
Thus, zero speed is at the left (anti-clockwise) position on the potentiometer.
Bi-directional Speed Setpoint
Alternatively, substitute A1 for terminal B4 to scale the input such that:
Maximum forward speed setpoint (+100%) =
Terminal B3, +10V input
Maximum reverse speed setpoint (-100%) = Terminal B4, -10V input
Thus, zero speed demand is at the centre position on the potentiometer.
