Parameters
2007 MINIMUM FREQ -500.0…500.0 Hz 0.1 Hz 0.0 Hz 
Defines the minimum limit for the drive output frequency.
• A positive or zero minimum frequency value defines two ranges,
one positive and one negative.
• A negative minimum frequency value defines one speed range.
See the figure.
Note: Keep
MINIMUM FREQ  MAXIMUM FREQ.
2008 MAXIMUM FREQ 0.0…500.0 Hz 0.1 Hz 60.0 Hz (US) 
Defines the maximum limit for the drive output frequency.
2013 MIN TORQUE SEL -6…7 1 0 (
MIN TORQUE 1)
Defines control of the selection between two minimum torque limits (2015
MIN TORQUE 1 and 2016 MIN TORQUE 2).
0 =
MIN TORQUE 1 – Selects 2015 MIN TORQUE 1 as the minimum limit used.
1 =
DI1 – Defines digital input DI1 as the control for selecting the minimum limit used.
• Activating the digital input selects
MIN TORQUE 2 value.
• De-activating the digital input selects
MIN TORQUE 1 value.
2…6 =
DI2…DI6 – Defines digital input DI2…DI6 as the control for selecting the minimum limit used.
•See
DI1 above.
7 =
COMM – Defines bit 15 of the Command Word 1 as the control for selecting the minimum limit used.
• 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 selecting the minimum limit used.
• Activating the digital input selects
MIN TORQUE 1 value.
• De-activating the digital input selects
MIN TORQUE 2 value.
-2…-6 =
DI2(INV)…DI6(INV) – Defines an inverted digital input DI2…DI6 as the control for selecting the minimum limit
used.
•See
DI1(INV) above.
2014 MAX TORQUE SEL -6…7 1 0 (MAX TORQUE 1)
Defines control of the selection between two maximum torque limits (2017
MAX TORQUE 1 and 2018 MAX TORQUE 2).
0 =
MAX TORQUE 1 – Selects 2017 MAX TORQUE 1 as the maximum limit used.
1 =
DI1 – Defines digital input DI1 as the control for selecting the maximum limit used.
• Activating the digital input selects
MAX TORQUE 2 value.
• De-activating the digital input selects
MAX TORQUE 1 value.
2…6 =
DI2…DI6 – Defines digital input DI2…DI6 as the control for selecting the maximum limit used.
•See
DI1 above.
7 =
COMM – Defines bit 15 of the Command Word 1 as the control for selecting the maximum limit used.
• 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 selecting the maximum limit used.
• Activating the digital input selects
MAX TORQUE 1 value.
• De-activating the digital input selects
MAX TORQUE 2 value.
-2…-6 =
DI2(INV)…DI6(INV) – Defines an inverted digital input DI2…DI6 as the control for selecting the maximum limit
used.
•See
DI1(INV) above.
