Rockwell Automation Allen-Bradley 160 SSC Series, User Manual

Page: 49 / 88

Parameters and Programming 5-11
51 [Restart Time]
Time between restart attempts.
If this parameter and P50 - [Restart Tries] are both set to zero, and P46 - [Input
Mode] is not set to 3, the auto fault clear feature is enabled. This feature
automatically clears overvoltage, undervoltage, and overtemperature faults 1
second after the fault condition is removed.
If this parameter is set to zero and P50 - [Restart Tries] is not zero, then the time
between restart attempts is 1 second.
0.0/300.0 0.1
Seconds 10.0
Seconds
52 [DB Enable]
Enables/disables external dynamic braking.
Setting “0” = Disable. Settings 1 through 100 = % duty cycle braking.
This parameter cannot be programmed while the drive is running.
0/100 Numeric
Value 0
53 [S-Curve]
Enables a fixed shape S-Curve. See formula below:
Formula: S-Curve Time = Accel or Decel Time x S-Curve Setting (in percent)
➊
➊
See values below.
Example: Accel Time = 10 Seconds
S-Curve Setting = 3
S-Curve Time = 10 x 0.3 = 3 Seconds
Important: Maximum S-Curve time is 60 seconds.

ATTENTION: The 160 Dynamic Brake Module is rated for 5%
duty cycle. Use of this package above 5% should not be used and
voids the UL rating of this device. When setting this parameter
to a value above 5% duty cycle, the resistor must be sized to avoid
overheating of the resistor package.
