 Setting of operation time (X13 signal, Pr.11)
• Set the time applying the DC injection brake to Pr.11 DC injection brake operation time.
• When the motor does not stop due to large load moment (J), increasing the setting produces an effect.
• When Pr.11 = "0 s", DC injection brake will not operate. (The motor will coast to stop.)
• When Pr.11 = "8888", DC injection brake will operate when the X13 signal is turned ON. DC injection brake will operate
when the X13 signal is turned ON even while operating.
• For the X13 signal input, set "13" in any of Pr.178 to Pr.189 to assign the function.
NOTE
• The X13 signal is disabled during PM motor control.
 Setting of operation voltage (torque) (Pr.12)
• Pr.12 DC injection brake operation voltage will set the percent against the power supply voltage.
• DC injection brake will not operate with setting of Pr.12 = "0%". (The motor will coast to stop.)
NOTE
• Even if the setting value of Pr.12 is made larger, braking torque will be limited so the output current will be within the rated
current of the inverter.
CAUTION
• Install a mechanical brake to make an emergency stop or to stay stopped for a long time.
