Function not used.
1
TREF used as analog torque limit.
2
TREF used as torque feed-forward input.
3
TREF used as analog torque limit when PCL and NCL are ON.
•
Set TREF (torque command input) function when using position control and speed control.
•
Set 1 to limit the output torque to the same value for both forward and reverse regardless of TREF
voltage polarity (read as an absolute value).
•
Set 2 to calculate torque corresponding to TREF voltage in the current loop (TREF voltage polarity
enabled).
•
Set 3 to limit the forward output torque during PCL input (forward current limit input), and limit the re-
verse output torque during NCL input (reverse current limit input), regardless of TREF voltage polarity
(read as an absolute value).
•
You can change the TREF voltage scale using Pn400 (torque command scale). Default setting: 3 V/
rated torque.
Note
Other torque limit functions include Pn402 (forward torque limit), Pn403 (reverse torque limit),
Pn404 (Forward rotation external current limit), and Pn405 (Reverse rotation external current lim-
it). The smallest output torque from among the enabled limitations is limited.

1
REF used as analog speed limit.
•
Set the REF (speed command input) function for torque control.
•
Set 1 to set REF voltage as the analog speed limit, regardless of polarity (read as an absolute value).
•
You can change the REF voltage scale using Pn300 (speed command scale). Default setting: 10 V/
rated rotation.
Note
Other speed limitation functions include Pn407 (speed limit). The speed is limited to the lower
value.
