PD31 Master-slave operation - Speed limit coefficient on slave
This parameter setting is used with servo amplifier with
software version C1 or later. Check the software version
using Setup software (SETUP221E).
This parameter is used to set an internal speed limit
value coefficient to speed limit command value received
from master axis. This parameter is enabled when this
amplifier is set as slave axis ([Pr. PD15] = "0010").
Convert a decimal value to a hexadecimal value for
input. The maximum value is 500. Setting over 500 will
be 500.
Setting 100 [%] (0064h in hexadecimal) means
multiplication of one.
Setting example: [Pr. PD31 (VLC)] = 0078h (120%), [Pr.
PD32 (VLL)] = 012Ch (300 r/min), and master side
acceleration/deceleration at 1000 [r/min]
0000h PD31 Master-slave operation - Speed limit coefficient on slave
This parameter is used to set an internal speed limit
value coefficient to speed limit command value received
from master axis.
This parameter is enabled when this amplifier is set as
slave axis ([Pr. PD15] is "_ _ 1 0".). The maximum value
is 500. Setting over 500 will be 500.
Setting 100 [%] means multiplication of one.
Setting example: [Pr. PD31 (VLC)] = 140 [%], [Pr. PD32
(VLL)] = 300 [r/min], and master side
acceleration/deceleration at 1000 [r/min]

PD32 Master-slave operation - Speed limit adjusted value on
slave
This parameter setting is used with servo amplifier with
software version C1 or later. Check the software version
using Setup software (SETUP221E).
This parameter is used to set a minimum value for
internal speed limit value.
This parameter is enabled when this amplifier is set as
slave axis ([Pr. PD15] = "0010"). Convert a decimal value
to a hexadecimal value for input. The speed limit value
will not be this setting value or lower.
This parameter ensures torque control range at low
speed driving (avoid area likely to reach speed limit). Set
100 to 500 [r/min] normally as a reference.
Refer to [Pr. PD31] for the setting example.
