Minarik Drive Parameters
Registers #0 through #50 (Modbus Registers #1 to #51) are reserved for Configuration and Control. Registers #51 through #255
(Modbus Register #52 to #256) are reserved for the Drives’ Programming Mode Parameters. Programming Mode Parameters are the
parameters that can be accessed from the local keypad on the drive. There is a direct correspondence between the AC200 Drive
Programming Mode Parameter number and the Minarik Register number (and consequently, the Modbus register number):
Minarik Register # = (AC200 Programming Parameter # ) + 50
Modbus Register # = (AC200 Programming Parameter #) + 51
The entries in Table 1 are based on AC200 Drive Software #213-064 Revision 03 (Parameter Configuration = 312). If a later
revision of software were to change register definitions, drive operation could be seriously affected. This will be identified for a
given drive by examining Register #50 (Parameter Configuration Number). The number displayed at power up on drive display can
also identify it. If it is not 312, writing to any register on the drive MUST NOT BE ATTEMPTED unless your Controller has been
setup to support the new configuration.
AC200 Operational Details
A) Serial Address
All Minarik drives have a Serial Address Parameter that must be programmed prior to attempting to operate the serial
interface (Programming Parameter #43 / Minarik Register #93).
B) Serial Communications Parameter
1) All Minarik drives have a Serial Communications Parameter that governs the operation of the Serial Link. On AC200
drives this is #15 SERIAL LINK (register #65). It has the following selections:
1 = DISABLE
2 = 9600, N, 2 WITH TIMER (10 sec) ← default
3 = 9600, N, 2 WITHOUT TIMER
4 = 9600, E, 1 WITH TIMER (10 sec)
5 = 9600, E, 1 WITHOUT TIMER
6 = 9600, O, 1 WITH TIMER (10 sec)
7 = 9600, O, 1 WITHOUT TIMER
Explanation of Terms:
• DISABLED - serial link not operational.
• WITH TIMER - serial link allows reading & writing of both control & programming parameters. Watchdog timer is
enabled (see “F” on page 5).
• WITHOUT TIMER - serial link allows reading & writing of both control & programming parameters. Watchdog timer is
disabled (see “F” on page 5).
2) Prior to attempting to communicate with the drive, Serial Communications Parameter must be appropriately
programmed.
C) Control Parameter
1) Programming parameter #14 (control) must be programmed to 01 (terminal strip only). Serial operation will not work
correctly if 02 (remote keypad only) or 03 (terminal strip or remote keypad) are selected.
D) Unlocking & Locking Controls
1) A write to Register #48 (Unlock Controls) with a value of 0 will unlock controls. This enables the writing of Register
#1 - the Drive Control Register and register #40 (keypad speed command).
Note: Terminal TB1 must be closed in order to unlock serial control.
2) If Register #48 (Unlock Controls) is written with a value that is the Drive’s Programming Password, then in addition to
Register #1 (Drive Control), writing to all other writeable registers is enabled (e.g.: register #81 - Preset Speed #1). The
factory default password for AC200 series drives is 225.
