SPEED FEEDBACK GAIN ( Alternate network map, drop_1, register 38 )
Only available if the AutoMax Network Communication board is installed.
Controls the gain of the speed loop feedback path.
This is typically a value that is related to the diameter of the roll in a winder application.
Parameter Range: 1000 to 32000 (gain of 1.000 to 32.000)
Default Setting: 1000
Parameter Type: Tuneable
OIM Menu Path(s): This parameter is available over the network, alternate network map,
drop_1, register 38. It cannot be viewed through the OIM or DCM.
Refer also to Parameters: CONTROL SOURCE SELECT (P.000),
NETWORK MAP SELECT (P.914)
To access this register, CONTROL SOURCE SELECT must be set to NETWORK and NETW
REGISTER MAP SEL (P.914) must be set to ALTERNATE.
To bypass the multiplier block, set this register to 1000 (1.000). This is also the value SPEED
FEEDBACK
GAIN is forced to when NETW REGISTER MAP SEL (P.914) is set to ORIGINAL.
ATTENTION: When CONTROL SOURCE SELECT is changed from NETWORK to another value, the
speed feedback multiplier block is bypassed. This can cause the motor to rotate faster than it did
when under network control. The active speed reference should be set to zero before starting the
drive from the new control source. The active speed reference is based on the new control source and
the auto/manual setting.
SPD LEADLAG LOW FREQ (P.214)
If LEAD/LAG is selected in SPD LEADLAG SELECT, this parameter represents the lead corner
frequency. If SPD LEADLAG SELECT is set to BYPASS, this parameter has no effect. If LAG/LEAD is
selected, it represents the lag corner frequency.
Parameter Range: 0.01 to 69.81 rad/s when FEEDBACK SELECT = ARMATURE VOLT
0.01 to 139.62 rad/s when FEEDBACK SELECT
≠ ARMATURE VOLT
Default Setting: 1.00 rad/s
Parameter Type: Tuneable
OIM Menu Path(s): Speed/Voltage Loop (SPD) - Speed/Voltage Loop (SPD) Tuning
Refer also to Parameters: SPD LEADLAG SELECT (P.216)
SPD LEADLAG RATIO (P.213)
Sets the ratio of low to high break frequencies for the lead/lag block. For example, if this parameter is
set to10, the high break frequency will be 10 times the low break frequency (specified by SPD
LEADLAG LOW FREQ). If SPD LEADLAG SELECT is set to BYPASS, this parameter has no effect.
Parameter Range: 2 to 20
Default Setting: 2
Parameter Type: Tuneable
OIM Menu Path(s): Speed/Voltage Loop (SPD) - Speed/Voltage Loop (SPD) Tuning

SPD LEADLAG SELECT (P.216)
