0=not used
1=Used by PLC
AFM
12
AO1 (optional)
AO2 (optional)
 For Example:
If Pr.03.10 displays 1, it means that AFM is used by PLC.
03.11 Brake Release Frequency Unit: 0.01
Settings 0.00 to 20.0Hz Factory Setting: 0.00
03.12 Brake Engage Frequency Unit: 0.01
Settings 0.00 to 20.0Hz Factory Setting: 0.00
 These two parameters are used to set control of mechanical brake via the output terminals
(Relay or MO1) by setting Pr.03.00~03.01.
 When Pr.03.00~03.01 is set to 21, the multi-function output terminal will be activated when the
output frequency reaches Pr.03.11. When the AC motor drive stops and the output frequency
reaches Pr.03.12, this multi-function output terminal will be activated.

 Example:
When using Pr.03.11 and Pr.03.12 are used in life equipment as above figure. The timing
figure is shown as follows. The DC brake is used before start-up and after stop. It can have
high output torque at the beginning of start-up. The Brake Release Frequency (Pr.03.11) can
be set by the requirement. The Brake Engage Frequency (Pr.03.12) can be set by requirement
to be used when stopping near 0Hz to prevent vibration of counterforce for smooth operation.
