H Control Input Details (CN1)
D 5: Speed Command Input (REF); 6: Speed Command Input Ground (AGND)
Speed Control
This is the input for speed commands. The scale of the rotation speed for REF voltage can be changed
by means of user parameter Pn300 (speed command scale). The default setting is for the rated rotation
speed for an input of 10 V.
Torque Control
This input becomes an analog speed limit input when Pn002.1 (speed command input change, of func-
tion selection application switch 2) is set to 1. The default setting is for the function to not be used (set
value: 0). The scale of the speed limit value for speed command inputs can be changed by means of
user parameter Pn300 (speed command scale).
The REF voltage is irrelevant (absolute values only).
The speed is limited to the Pn407 (speed limit) setting or the REF voltage limit, whichever is lower.
Position Control
This input becomes a speed feed forward input when Pn207.1 (speed command input change) is set to
1. The default setting is for the function to not be used (set value: 0). A speed command corresponding
to the REF voltage is added to the speed loop.
D 9: Torque Command Input (TREF); 10: Torque Command Input Ground (AGND)
Torque Control
This is the input for torque commands. The scale of the output torque for TREF voltage can be changed
by means of user parameter Pn400 (torque command scale). The default setting is for the rated torque
for an input of 3 V.
Position and Speed Control
This input becomes an analog torque limit input (set value: 1 or 3) or a torque feed forward input (set
value: 2) depending on the Pn002.0 (torque command input change, of function selection application
switch 2) setting.
The scale of the torque limit value or the feed forward torque for TREF voltage can be changed by
means of user parameter Pn400 (torque command scale). The default setting is for the rated torque for
an input of 3 V.
Pn002.0 = 1: Analog Torque Control Input
Output values for both forward and reverse are limited by the same value, regardless of the TREF volt-
age polarity (the absolute value is used). See the note below.
Pn002.0 = 2: Torque Feedforward Input
A torque corresponding to the TREF voltage is added to the current loop. The TREF voltage polarity is
effective.
Pn002.0 = 3: Analog Torque Limit Input when Inputting PCL and NCL
The TREF voltage polarity is ignored (the absolute value is used). When PCL (forward rotation current
limit input) is input, the output torque for forward rotation is limited. When NCL (reverse rotation current
limit input) is input, the output torque for reverse rotation is limited. See the note below.
