All control options are subject to the Parameter and Control Locking/Unlocking procedures.

4.4 Unlocking & Locking Controls

Registers #48 and #1 are used in Unlocking and Locking Controls.

• 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.

• 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

#52 -- Preset Speed #1). The factory default password for MC series drives is 19.

• Once Register #48 (Unlock Controls) has been written, Controls are unlocked until the Lock Security

ﬂag (Bit 1 of Register#1) has been set or until a Watchdog Timeout occurs.

• Writing to Register #1 (Drive Control) with bit 1 set will Lock both Controls and Parameters (prevents

writing to any register).

• The serial drive control can only be unlocked when the drive is not in programming mode.

• When LOCK is asserted, the drive drops out of SERIAL control and reverts back to the previous source

of control.

• Even though drive might be locked, and thus parameters and control cannot be written, parameters

and status can always be read. Refer to section 4.7,

Monitoring Only Operation

4.5 Unlocking & Locking Programming Parameters only

Registers #49 and #1 are used in Unlocking and Locking Programming Parameters.

• Writing to any writeable register other than #1 can be enabled by writing the Drive’s Programming

Password to Register #49 (Unlock Parameters). This would be done when Drive Control (start, forward/

reverse, keypad speed control, etc.) is not required.

• The Factory Default password is 19.

• Once Register #49 (Unlock Parameters) has been written, the writing of parameter registers is enabled

until Bit 1 of Register #1 has been set.
