The AccuMax is an all-solid-state control for 90 or 24 VDC clutches and brakes. Built-in over-energization ensures fast response time and excellent repeatability.

Logic level input permits direct interface with PLC output modules, photoelectric controls, proximity sensors, contacts, transistors, etc.

Adjustable switching time delay lets you minimize overlap between the clutch and brake, which means longer mechanical life.

NOTES

1. Logic terminals 1,2 on the AccuMax-120 and AccuMax-32 are isolated. Terminal L2 or T2 and/or 2 may be grounded.

2. Logic voltage on the AccuMax-V12 is 12 VDC from internal power supply. Initiating contact may be any contact, transistor, reed switch, etc. capable of switching 12 VDC, 1mA.

3. Load terminals A,B,C and terminal 3 are not isolated from line terminals L1,L2 or T1,T2 and must not be connected to ground.

4. Do not place switches or mechanical contacts between clutch and brake and their terminals A,B,C. Opening these circuits while current is flowing may damage the control.

OPERATION (refer to TIMING DIAGRAM)

AccuMax-120 and AccuMax32

a. When power is applied to L1,L2 or T1,T2 with no logic voltage present, the brake energizes.

b. When logic voltage is applied to 1,2 brake immediately de-energizes. Clutch is energized following preset Switching Time Delay.

c. When logic voltage is removed, clutch de-energizes and, following Switching Time Delay, brake energizes.

AccuMax-V12

Maintained 2-wire (1 SPST switch)

a. When power is applied to L1,L2 or T1,T2 with 1,3 contacts open, brake energizes.

b. Maintained closure of 1,3 contacts causes brake to de-energize. Clutch is energized following Switching Time Delay.

c. When 1,3 contacts open, clutch de-energizes and, following Switching Time Delay, brake energizes

Maintained 3-wire (1SPDT switch)

a. When power is applied to L1,L2 or T1,T2 with 2,3 contacts closed, brake energizes.

b. When 2,3 contacts open and 1,3 contacts close, brake de-energizes. Clutch is energized following Switching Time Delay.

c. When 1,3 contacts open and 2,3 contacts close, clutch de-energizes and, following Switching Time Delay, brake energizes.

Momentary (2 SPST switches)

a. When power is applied to L1,L2 or T1,T2 with 1,3 and 2,3 contacts open, brake energizes.

b. Momentary closure of 1,3 contacts causes brake to de-energize. Clutch is energized following Switching Time Delay.

c. Momentary closure of 2,3 contacts causes clutch to de-energize. Brake is energized following Switching Time Delay.

d. With 1,3 and 2,3 contacts closed, 1,3 contacts override and clutch energizes.

TIMING DIAGRAM


SWITCHING TIME DELAY

Switching Time Delay is a delay between clutch turn-off and brake turn-on, and vice versa, to reduce overlap. By adjusting this delay, you can obtain the fastest cycle time and the least wear on your mechanical system. With the Switching Time Delay control fully clockwise (10), switching time delay is at its maximum (approx. 100 msec). Fully counter-clockwise (0) provides the minimum delay. Correct setting depends upon clutch/brake size, response time, and load inertia. Flux rise time in clutch or brake coil is independent of Switching Time Delay.

OVERLOAD PROTECTION

If clutch or brake coil current rises above a preset level, an overload circuit turns off the clutch and brake to protect the output switches. Power to the AccuMax must be removed and reapplied to reset the overload protection circuit.

6,7 JUMPER

For fastest flux rise time, install 6,7 Jumper. Remove 6,7 jumper for coil resistance greater than 500 ohms (for AccuMax90) or 250 ohms (for AccuMax24). If 6,7 jumper is installed and coil resistance is too high, over-energization may not occur each cycle.

Regents AccuMaxTM

Clutch/Brake Control with Over-Energization

OPTIONS (R,P,O,S)

The following options are available for Regents AccuMax90 and AccuMax24 Clutch/Brake Controls.

FIXED SWITCHING TIME DELAY (R)

Description: Instead of a knob to adjust switching time delay, the AccuMax can be supplied with a fixed resistor installed on the two terminals labeled RT. The resistor normally supplied has a value of 82K, which provides a nominal 82 msec switching time delay. At your request, Regent will supply any standard value resistor up to 100K. Time to resistance ration is 1msec/1K (+/-20%). Note: If R option is specified, a resistor must be installed on RT terminals to ensure proper operation.
Application: Use this option when the switching time delay should not be changed. This allows the design engineer or plant manager to set timing, but prevents adjustment by operators.
Ordering: Add the suffix letter R, for example AccuMax90-32R.

INTERNAL SENSOR POWER SUPPLY (P)

Description: The AccuMax can be supplied with a built-in 12 VDC power supply (+/-10%, 1V p-p max ripple, 150mA). The output of the internal power supply appears on terminals +,- and is electrically isolated from other AccuMax terminals.
Application: The 12 VDC internal power supply is ideal for powering photoelectric and 3-wire DC proximity sensors used with the AccuMax.
Ordering: Add the suffix letter P, for example AccuMax90-32P.

OVERRIDE INPUT (O)

Description: This option adds flexibility to the control of the AccuMax. An override signal causes both outputs (brake and clutch) to de-energize. The override input can be any voltage from 3 to 32 VDC. Apply the signal to terminals 4,5 (positive to 4) and both loads will de-energize regardless of logic signal on terminals 1,2.
Application: Order this option if both loads must be off for machine setup or manual positioning.
Ordering: Add the suffix letter O, for example AccuMax90-32O.

SINGLE CHANNEL (S)

Description: One output (terminals A,C) with no switching time delay.
Application: Use this option when only one load needs to be controlled. With no switching time delay, response to logic input is quicker.
Ordering: Add the suffix letter S, for example AccuMax90-32S.
