 When Not Using a
Dynamic Brake
• Set Pn001 = n.X
to 2 (Coast the motor to
a stop without the
dynamic brake).
• Set Pn601 and Pn604
to 0.
 When Using a Dynamic
Brake
• Set Pn001 = n.X
to 0 (Stop the motor by
applying the dynamic
brake) or 1 (Stop the
motor by applying the
dynamic brake and then
release the dynamic
brake).
• Set Pn601 and Pn604
according to the specifi-
cations of the resistor.
