The percentage command for the Initial Hold Level.
X= 5 – 10 for the VCL name Driver_X_Hold_Level
This is the percentage the driver will initially “jump to” without
ramping. This is affectedly the traditional contactor pull-in
parameter. For example, a high pull-in ensures contactor contact-
tips closure or a fast EM Brake release.
Direct PWM: This is the pulse width percentage.
Voltage Comp: This is nominal voltage percentage.
(Note, Coil Return = B+ voltage)
Current Cntrl: This is percentage between the maximum
and minimum driver current setting.
(See the Current Control parameters menu,
below)
Note that the Initial level may be above or below the applied
command.
Hold Time
Driver_X_Hold_Time
Parameter’s CAN Index by
Driver_X_Hold_Level
5 = 0x3164 0x00
6 = 0x3165 0x00
7 = 0x3166 0x00
8 = 0x3167 0x00
9 = 0x3168 0x00
10 = 0x3169 0x00
0 – 10000 ms
0 – 10000
0 ms
0
The time the Initial Level is applied.
X= 5 – 10 for the VCL name Driver_X_Hold_Time
This parameter allows customization of the driver’s initial-level
parameter duration, before any ramping to the longer-term
command percentage.

5 = 0x31B4 0x00
6 = 0x31B5 0x00
7 = 0x31B6 0x00
8 = 0x31B7 0x00
9 = 0x31B8 0x00
10 = 0x31B9 0x00

Drivers 9 and 10 offer a “oat” state, where the input is neither
pulled-up to +5V nor pulled-down to ground. These two drivers
oat option are for interfacing with TTL device.
X= 9 – 10 for the VCL name Switch_X_Open_State
