SIMOVERT MASTERDRIVES
The frequency set command is initiated by the user. First he writes
the new setpoint into register set frequency (RWwm+1). Second he
activates the command with the control bit frequency set command
request (RYnD). After the CBL has written the new value to the
converter it acknowledges with frequency setting complete (RXnD).

Check, that P443 Source main setpoint is set to communication board
PZD2 (first CBL => 3002)!
With RL, RM and RH you have 3 selectable fixed setpoints. You have
to parameterize the fixed setpoint buffer:
fixed setpoint (1) =>
fixed setpoint (2) =>
fixed setpoint (3) =>
fixed setpoint (4) =>
After you have selected P443 = 0040 (Source main setpoint = fixed
setpoint buffer ) you can control the speed by the control bits RL, RM
and RH. If you activate more than one bit of them, the lower speed has
the higher priority. The control bits JOG1 (RYn5) and JOG2 (Ryn7)
have higher priority than RL, RM and RH.
Priority: High <= JOG RL RM RH => Low
The JOG function can be activated by control bits JOG1 (RYn5) or
JOG2 (RYn7). JOG1 is assigned to "JOG setpoint 1" and JOG2 is
assigned to "JOG setpoint 2" of the converter; refer to its
documentation. The JOG setpoints in the converter are signed integer
values in percent; so speed and direction at JOG mode can be handled
by the user.
Don't use STF and STR to control direction at JOG mode! Refer to
function diagrams of converter.
