Mitsubishi Electronics FR-S500 instruction manual DC injection brake Pr , Pr , Pr, Changed to 4%

Explanation of functions (parameters)

2.3.7DC injection brake (Pr. 10 , Pr. 11 , Pr. 12 )

By setting the DC injection brake voltage (torque), operation time and operation starting frequency, the stopping accuracy of positioning operation, etc. or the timing of operating the DC injection brake to stop the motor

Output frequency (Hz)

Pr.10

"Operation

can be adjusted according to the load.

Pr.12

Pr.11 "Operation time"

Parameter	Name	Factory	Setting	Remarks
		Setting	Range
	DC injection brake			Setting is enabled when
10		3Hz	0 to 120Hz
	operation frequency			Pr. 30 = "1".
11	DC injection brake	0.5s	0 to 10s	(When Pr. 11 is set to "0s" or
	operation time			Pr. 12 is set to "0%", DC
12	DC injection brake voltage	6%	0 to 15%	injection brake is not
				operated.)

* The factory setting varies according to the inverter capacity. (Refer to the following table for details.)

<Setting>

•Use Pr. 10 to set the frequency at which the DC injection brake operation is started.

•Use Pr. 11 to set the period during when the brake is operated.

•Use Pr. 12 to set the percentage of the power supply voltage.

•Change the Pr. 12 setting to 4% when using the inverter-dedicated (constant-torque motor).

(If the Pr. 12 value remains unchanged from the factory setting and Pr. 71 is changed to the setting for use of the constant-torque motor, the Pr. 12 setting is automatically

changed to 4%.)

.

CAUTION

Install a mechanical brake. No holding torque is provided.
