Follower torque reference selection “FollowerTorq sel”
Select the source of torque reference for the follower drive.
0 = ”Not Used”
1 = ”AI1” – Analog Input 1
Signal scaling in “G: Input Signals\Analog Input 1”
2 = ”AI2” – Analog Input 2
Signal scaling in “G: Input Signals\Analog Input 2”
3 = ”AI3”
4 = ”AI4”
5 = ”AI1 Joystick”
Analog input 1, –10 Vdc... +10 Vdc. For joystick inputs, the maximum negative
reference is the negative of “Torq Ref Max”.
6 = ”AI2 Joystick”
Analog input 2, –10 Vdc... +10 Vdc For joystick inputs maximum negative reference
is the negative of “Torq Ref Max”.
7 = ”Keypad Ref”Torque reference from keypad R3.5
8 = ”Fieldbus”
Reference is taken from fieldbus. Alternative scaling can be selected in “G:
Fieldbus”
9 = ”Master Torque”
Reference is taken from Master drive when using the Master Follower function.

Follower stop function “FollowerStopFunction”
When the follower drive does not use the Master Drive Ramp Output as reference this
parameter defines how the follower drive will stop as Run request is removed from the
Master drive.
0 = Coasting; the follower remains in control even if master has stopped to fault
1 = Ramping; the follower remains in control even if master has stopped to fault
2 = As master; the follower behaves as master

Master follower brake logic “MF brake logic”
This parameter defines brake functionality when operating Master-Follower mode.
This parameter is not active when follower is operating in Ramp Follower mode (i.e.
Follower reference selection is “18 = Master Ramp”) or follower is a DriveSynch
follower. In these cases follower brake is controlled by master drive.
0 = Master or Own (Default)
Brake is opened when master or follower brake opening conditions are met in
follower drive.
1 = Own
Brake is opened when follower drive own brake opening conditions are met. Also
brake is close if follower drive own conditions are met regardless of master status.
2 = Own & Master Speed Release
Brake is opened when follower drive own brake opening conditions are met. Also
brake is close if follower drive own conditions are met regardless of master status.
But Speed is not released until drive has the feedback from the brake, actual or
defined by Mechanical Brake Delay parameter and master has released speed.
When this selection is made also in Master drive, Speed is not released until
master drive has the feedback from the brake actual or defined by Mechanical
Brake Delay parameter also from followers
3 = Master
Master drive is controlling follower drive brake and speed release.
When follower reference selection
is 17 = “Master
Ref”, speed limitation function
from brake control are
bypassed on follower side.

Master Follower mode 2 selection “MF mode 2”
Selects the Master Follower mode 2 that is used when the DI is activated. When
Follower is selected the Run Request command is monitored from Master and all other
references are selectable by parameters. This parameter can be used for redundancy
purposes. If drive number one is unable to be operated through a digital input drive
number 2 can be selected as master.
0 = Single Drive System bus is deactivated.
1 = Master Drive sends control word to follower drive.
2 = Follower
Drive received control word from Master and sends some diagnostic information to
the Master drive.
3 = “DSynchMaster” - Drive Synch Master
Drive number 1 must be selected as the parallel drive configuration master (in
redundancy mode drive number 2 can be selected as master but certain diagnostic
functions are no longer available).
