6.2.6.2 Object 0x5520: Setpoint parameter
The axis velocity setpoint value parameter <VelSetpointParameter> (0x5520) points to the input where the
axis velocity setpoint value <VelSetpoint> (0x6500) comes from.
The axis velocity setpoint value <VelSetpoint> (0x6500) is only effective in case the <StatusWord> (0x6041)
is 1111
b
('ACTIVE') and the <DeviceMode> (0x6042) is set to 1 (setpoint input via bus).
Value description
This pointer contains a combination of index, sub-index and length of the parameter to be used.
The default value is 0x65000120, which refers to the <VelSetpoint> (0x6500), sub-index 0x01 with the length
of 32 bit (32 = 0x20).
6.2.6.3 Object 0x5527: Hold setpoint
This parameter defines the axis velocity hold setpoint value. This parameter is in effect only for the
<ControlMode> (0x6043) = 6 (axis velocity control).
Chapter "7.1.1 Object 0x6043: Control mode", page 128
The <VelHoldSetpoint> (0x5527) acts as setpoint value in case of <StatusWord> (0x6041) equals 'HOLD' or
'FAULT_HOLD'.
