Programming Guide
Parameter 42-44 Deceleration Rate
Table 1392: Parameter 42-44 Deceleration Rate
42-44 Deceleration Rate
Default value: 1500/s
Conversion index: 0
Deceleration rate for the SS1 slope-based ramp type.
Parameter 42-45 Delta V
Table 1393: Parameter 42-45 Delta V
42-45 Delta V
Default value: 120 RPM
Conversion index: 67
Tolerance between calculated and actual speed that the safety option allows.
Parameter 42-46 Zero Speed
Table 1394: Parameter 42-46 Zero Speed
42-46 Zero Speed
Default value: 10 RPM
Conversion index: 67
When this speed is reached, the safety option activates the STO.
Parameter 42-47 Ramp Time
Table 1395: Parameter 42-47 Ramp Time
42-47 Ramp Time
Default value: 1 s
Conversion index: 0
The time it takes to ramp down to 0 RPM.
Parameter 42-48 S-ramp Ratio at Decel. Start
Table 1396: Parameter 42-48 S-ramp Ratio at Decel. Start
42-48 S-ramp Ratio at Decel. Start
Default value: 50%
Conversion index: 0
The proportion of the total ramp-down time (parameter 42-42 Delay Time) where the deceleration torque increases. The larger the
percentage value, the greater the jerk compensation achieved, and thus the lower the torque jerks in the application.
Parameter 42-49 S-ramp Ratio at Decel. End
Table 1397: Parameter 42-49 S-ramp Ratio at Decel. End
42-49 S-ramp Ratio at Decel. End
Default value: 50%
Conversion index: 0
