EM500 Open-Loop Vector Control Inverter User Manual F00.21=0: Permit forward/reverse The rotation direction of motor can be controlled by the set F/R terminal or F00.20. F00.21=1: Prohibit reverse Motor can run at one direction only and neither terminal F/R nor F00.20 is enabled. Select the status when motor switches between forward and reverse. If F00.22=0.00, the switch between forward and reverse completes smoothly. at the reverse direction until the set frequency is reached, after the rotation speed If F00.22≠0, then inverter runs for the time set through F00.22 at 0.00 Hz and runs decreases to 0.00 Hz at the time of switching between forward and reverse. See Figure 7–5 for details.
Output frequency F/R Deadband Time F/R Deadband Time Time Figure 7–5 Forward/Reverse Deadband Time Inverter judges the direction according to the status of terminal F/R and the value set through F00.20. If the set forward direction is inconsistent with the wished motor direction, switch any two of inverter’s output terminals U, V and W, or change F00.20 to an inverse value. 168 No. Function Range Unit Default Type F00.21 Reverse Control 0: Permit forward/reverse 1: Prohibit reverse 0 〇 F00.22 F/R Deadband Time 0.00 - 650.00 s 0.00 ● No.
