Parameters
2208 EMERG DEC TIME
Sets the deceleration time for maximum frequency to zero for an emergency.
• See parameter 2109
EMERG STOP SEL.
• Ramp is linear.
2209 RAMP INPUT 0
Defines control for forcing the ramp input to 0.
0 =
NOT SEL – Not selected.
1 =
DI1 – Defines digital input DI1 as the control for forcing the ramp input to 0.
• Activating the digital input forces ramp input to 0. Ramp output will ramp to 0 according to the currently used ramp
time, after which it will stay at 0.
• De-activating the digital input: ramp resumes normal operation.
2…6 =
DI2…DI6 – Defines digital input DI2…DI6 as the control for forcing the ramp input to 0.
• See
DI1 above.
7 =
COMM – Defines bit 13 of the Command Word 1 as the control for forcing the ramp input to 0.
• The Command Word is supplied through fieldbus communication.
• The Command Word is parameter 0301.
-1 =
DI1(INV) – Defines an inverted digital input DI1 as the control for forcing the ramp input to 0.
• De-activating the digital input forces ramp input to 0.
• Activating the digital input: ramp resumes normal operation.
-2…-6 =
DI2(INV)…DI6(INV) – Defines an inverted digital input DI2…DI6 as the control for forcing the ramp function
generator input to 0.
• See
DI1(INV) above.
