When the motor is
stopped
Mechanical brake
Action setting
•
Define the action from the mechanical brake during motor stall
(output terminal BRK The delay time from ON to OFF) to the motor
current cutoff;
•
This parameter should not be less than the mechanical brake delay
time (Tb) to avoid electricity
Small displacement of the machine or the workpiece falls
•
See Figure 7.5 for the timing.

When the motor is
running
Mechanical brake
Action setting
•
Define the motor current cut to the mechanical brake during motor
operation the delay time (output terminal BRK changes from ON to
OFF).
•
This parameter is to decelerate the motor from high speed rotation
to low speed. Then actuate the mechanical brake to avoid damaging
the brake.
•
The actual operating time is required for PA48 or motor deceleration
to PA49 value Time, the minimum of the two.
•
l See Figure 7.6 for the corresponding timing.

When the motor is
running
Mechanical brake
Speed of action
•
Define the motor current cut to the mechanical brake during motor
operation The speed value of the output terminal BRK from ON to
OFF.
•
The actual operating time is required for PA48 or motor deceleration
to PA49 value Time, the minimum of the two.
•
See Figure 7.5 for the timing.

Torque control
Speed limit
•
During torque control, the motor running speed is limited to this
parameter;
•
It can prevent overspeed in light loads.

Dynamic electronic
tooth
Effective round
•
Set to 0, the dynamic electronic gear is invalid, the function of the
input terminal INH The command pulse is disabled.
•
Set to 1, dynamic electronic gear is valid, input terminal INH function
It is an electronic gear switch. When the INH terminal is OFF, input
electronic teeth The wheel is PA12/PA13; when the INH terminal is
ON, the input electronic gear
PA52/PA13; change the electronic gear ratio by controlling the INH
terminal Example value.

Second position
Pulse division
Molecule
•
The division frequency (electronic gear) of the second position com
-
mand pulse is set.
•
The dynamic electronic gear must be set with the parameter PA51=1,
at this time input Terminal INH (command pulse inhibit) function is
changed to electronic gear switching Enter the control terminal.
